OHMS LAW.pptx
Ohm's law describes the relationship between voltage, current, and resistance in electrical circuits. It states that the current through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor. The document provides an analogy comparing current in a wire to water flow in a hose and explains how increasing voltage or decreasing resistance increases current, similar to opening a tap wider or narrowing the hose. It also summarizes the key differences between series and parallel circuits, noting that current is the same in all parts of a series circuit while both current and voltage can vary in a parallel circuit.

Ohm's law describes the relationship between voltage, current, and resistance in electrical circuits. It states that the current through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor. The analogy is made that current is like water flowing through a hose - increasing the voltage is like opening the tap wider to increase flow, and increasing resistance is like stepping on the hose to decrease flow. A series circuit has resistors arranged in a chain so current has only one path, and the total voltage across all components equals the battery voltage. In a parallel circuit, the current splits across branches but the voltage is the same everywhere.

Ohms_Law.ppt
Ohm's law describes the relationship between current, voltage, and resistance in electrical circuits. It can be understood by comparing current flowing through a wire to water flowing through a hose. Increasing the voltage is like opening the tap wider to increase flow, while increasing resistance is like stepping on the hose to decrease flow. A series circuit has resistors arranged in a single path so the current is the same through each, while the voltage splits evenly across components. In a parallel circuit, the current splits across paths while the voltage remains the same everywhere.
Series circuits ad parallel circuits
A parallel circuit contains multiple paths for electricity to flow. The voltage is equal across all components, while the current through each component depends on its resistance. The total resistance of a parallel circuit is always less than any individual branch resistance, and decreases as more branches are added. Unlike a series circuit, if one component fails in a parallel circuit the others can still function.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

OHMS LAW.pptx
- 1. OHMS LAW Mr. S MARIA ANTONY
- 2. - Current: The path an electric current follows - Unit for current is amp - An ammeter measures the amount of current flowing past a certain point
- 3. Understanding Ohm’s Law Ohm’s law may be easier to understand with an analogy. Current flowing through a wire is like water flowing through a hose.
- 5. Increasing voltage with a higher- volt battery increases the current. This is like opening the tap wider so more water flows through the hose.
- 6. Increasing resistance reduces the current. This is like stepping on the hose so less water can flow through it.
- 7. Increasing the resistance, decreases the flow of current…
- 9. A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor.
- 10. You need to be aware of the following rules to work through the next questions. - Current in a series circuit is the same at all parts in a circuit. In a series circuit, the total, or sum of the voltages across all the components will equal the voltage across the cell/battery. - The total voltage supplied by the cell is 12V. There are three lamps connected in series, so 12/3 = 4V.
- 11. - The parallel circuit splits into each routes; - Example: - This means the current also splits into 3 equal amounts. Therefore, 9/3 = 3Amps - The voltage will be the same everywhere
- 12. Questions: The label on the battery says 6V. If we connected a voltmeter across each lamp, what would the readings be? At lamp 1 - ________V At lamp 2- ________V At lamp 3- ________V
- 13. Questions What type of circuit is this? What voltage will load 1, 2 and 3 have ? What current will Load 1, 2 and 3 have? 9 V L1 L2 L3
