Electric Charge

The electric charge is given by:

Q = It

Corresponding SI units:
coulomb (C) = ampere (A) ∙ second (s)

Where I is the electric current and t is the time (duration).

Example: Determine the electric current in an electric circuit where the total electric charge is 6 C over 5 seconds.

Isolating I from Q = It:

I = Q/t = 6 / 5 = 1.2 A
