In this lesson, we will learn how to use the formula I = Q/t to calculate the current through a point in simple circuits given the charge moving past that point in a given time.

Q1:

The diagram shows a circuit consisting of a battery and a resistor. The current through the circuit is 2.0 A. Over a period of 45 seconds, how much charge flows past point P in the circuit?

Q2:

Which of the following is the correct formula for the amount of charge flowing through a point in a circuit in a given time? π represents the amount of charge, πΌ represents the current, and π‘ represents time.

Q3:

Which of the following is the correct unit for electric charge?
