AQA GCSE Physics (8463) — Electricity
What You Need to Know
Explain that for electrical charge to flow through a closed circuit, there must be a source of potential difference.
Define electric current as the rate of flow of electrical charge.
Calculate charge flow using the equation:
Q
=
I
t
Q = I t
Q
=
I
t
Understand that current has the same value at any point in a single closed loop.
