This video breaks down the terminology encountered in grade 10 physical sciences' electric circuits. By watching this video, learners will be able to define terms like potential difference, current and resistance. The video will also help you understand why batteries go flat. In addition, there are worked examples to help us master calculations in electric circuits

Chapters:
00:00 Introduction
1:05 Revision
4:26 Potential difference
9:35 Emf
11:08 Why do batteries go flat?
14:40 Current
22:34 Resistance
25:12 Factors affecting resistance
28:25 Relating energy transferred, W, with V, I and t.
33:45 Example 1
35:13 Example 2
36:40 Example 3

Example 1: Calculate the resistance if the voltage is 12V and the current flowing is 6A.

Example 2: A 45C charge moves past a point in 1 second. What is the current in the circuit.

Example 3 A battery transfers 120J of energy to a 10C charge.
i. Calculate the voltmeter reading
ii. Calculate the ammeter reading when the 10C charge passes the ammeter in 5,18 seconds.
