Electricity is one of the most practical and high-yield chapters in the Form 2 syllabus. It bridges the gap between abstract physics and the real world (think: why does your phone charge?). In this post, we break down the you need to know and provide a set of electricity exercises to test your understanding.

Always connect in parallel across the component.

Ohm’s Law connects them all: $$V = I \times R$$

Use the words from the box:

Measures potential difference (voltage); connected in . A circle with a 'V'. Switch

Before you can solve any calculation problem, you need to understand the relationship between the three main characters in an electric circuit. Memorize this triangle!

A) Current B) Potential difference C) Resistance D) Power
