## 58 physics - circuit measuringPresentation Transcript

• [ Name ] [ Date ] Measuring Circuits
• Ammeters are used to measure the current (in amperes) in different parts of series & parallel circuits. When measuring, they are connected in series with the component that you are observing.
• A A SERIES CIRCUIT PARALLEL CIRCUIT
• Remember that in a series circuit, the current is the same everywhere. In a parallel circuit, the current is shared between the components, so is not always equal 2A 2A 2A 2A2A 1A 1A
• Copy the following circuits and fill in the missing ammeter readings. ? ? 4A 4A 4A 3A? ? 1A ? 3A 1A 1A
• Voltmeteres are used to measure the voltage (in volts) in different parts of series & parallel circuits. When measuring, they are connected in parallel with the component that you are observing.
• SERIES CIRCUIT PARALLEL CIRCUIT V V
• Remember that in a series circuit, the voltage is distributed across the components. In a parallel circuit, the voltage is equal in each component. 1.5V 1.5V 3V 3V 3V 3V
• Copy the following circuit diagram and fill in the missing current and voltage readings V V 6V 4A A A
• Copy the following circuit diagram and fill in the missing current and voltage readings 3V 3V 6V 4A 4A 4A
• V V 6V 4A A A A Copy the following circuit diagram and fill in the missing current and voltage readings
• 6V 6V 6V 4A 4A 2A 2A Copy the following circuit diagram and fill in the missing current and voltage readings
