Do now! Can you continue the sheet you started last lesson? (“Another current model”)

Series circuits The current (electrons) is the same in all parts of the circuit 2.4 A

Parallel circuits The current (electrons) splits, but the total current stays the same. 2.4 A 1.2 A 2.4 A

Voltage?

Voltage = Energy received or given by the electrons ☺ ☺ ☺ ☺ ☺ ☺ ☺ energy electron ☺ ☺ ☺ ☺

Measuring voltage The voltmeter is always connected across the component you’re measuring

Measuring voltage Can you complete the sheet “Measuring voltage”? Don’t let Mr Porter forget that he needs to collect your books at the end of the lesson.

In a series circuit The voltage across the cell is equal to the sum of the voltages across the lamps 9 V 3 V

In a parallel circuit The voltage across the cell is the same as across each lamp. 5 V
