What must a closed circuit include for electrical charge to flow?
Show answer
A source of potential difference (e.g. a cell or battery).
Define electric current.
Show answer
A flow of electrical charge.
What does the size of an electric current measure?
Show answer
The rate of flow of electrical charge (charge flowing per second).
What is the equation linking charge flow, current and time?
Show answer
Charge flow = current × time, or Q = I t.
The unit of charge flow (Q) is the ?, C.
Show answer
coulomb
The unit of electric current (I) is the ?, A.
Show answer
ampere
What symbol represents charge flow in Q = It?
Show answer
Q, measured in coulombs (C).
How much charge flows when 2 A runs for 30 s?
Show answer
Q = I t = 2 × 30 = 60 C.
How does current vary at different points in a single closed loop?
Show answer
It doesn't — the current has the same value at any point in a single closed loop.
What is the SI unit of time used in Q = It?
Show answer
The second (s).
