GCSE Physics - Charge, Current & Time #16

The video tutorial explains the concept of electric charge, using a water analogy to illustrate how charge is the total current that flows over time. Charge is represented by the letter Q and measured in coulombs. The fundamental equation for charge is given as charge equals current in amps multiplied by time in seconds. Two examples are provided: one involving a kettle to calculate charge, and another involving a phone charger to determine current. The tutorial also covers unit conversion and equation rearrangement for solving problems.

What is the definition of charge in the context of electric current?

How is charge represented and what unit is it measured in?

What is the equation used to calculate charge?

In the kettle example, how much charge passed through the wire?

How do you rearrange the equation to find current when given charge and time?
