Mr. Baldwin gave a lesson on parallel and series circuits. In a series circuit, all elements are connected consecutively so that removing one breaks the circuit and the same current flows through each. In a parallel circuit, elements are connected separately so removing one does not affect the others and voltage is shared while current depends on resistance. Students then worked in groups on an activity worksheet to practice identifying and comparing series and parallel circuits.

1. Mr. Baldwin Parallel and Series Circuits

2. All elements connected consecutively Removing one light breaks circuit Same current in both lights Series Circuit

3. How to Wire a Series Circuit!

4. Elements connected separately Remove one light, the others still work normally Voltage the same across each element Parallel Circuit

5. How to Wire a Parallel Circuit!

6. Lets watch a Video!:

7. Arrows show direction of current flow Voltage across each resistor element is equal Current varies based on resistance, V=IR, so I=V/R Voltage/Current in Parallel

8. All lights (resistors) share the same current flow Total resistance = sum of all resistors (lights) R Total =R1+R2+R3+R4 V=IR, so I=V/R Total R1 R2 R3 R4 Current and Voltage in Series

9. Voltmeter- measures voltage (V) Ammeter- measures current (I) Multimeters measure both! Multimeters!
