Charge and Current | GCSE Physics Practice Questions
Current is the flow of electric charge, usually carried by electrons in a metal conductor.
How quickly can you calculate charge flow?
What is Charge and Current | Practice Questions?
"The flow of electric charge per unit time."
Question 1
Current is the rate of flow of ____.
Question 2
Misconception: When a circuit is closed, the 'spent' current returns to the battery.
Question 3
A current of 0.5A flows for 2 minutes. Calculate the charge flow.
Current & Charge Facts
Current is measured in Amperes (A).
Charge flow = current x time (Q=It).
Charge is measured in Coulombs (C).
Exam Tip
Math Tip: Time must ALWAYS be in seconds for these formulas. Convert minutes or hours first!
