GCSE Physics

A current of 2 A flows for 30 seconds through a lamp.
How much charge has moved?

The formula is:

International notation of the formula for current and charge

which translates to:

Formula for current, charge and time.

Hence:

2 = Q / 30

2 × 30 = Q

60 = Q

Q = 60 coulombs

(60 coulombs of charge has moved.)
