Current flows from positive to negative in a circuit as electrons move. Current is measured in amps and represents the flow of charge over time, with charge measured in coulombs. The relationships between current, charge, and time can be remembered with the equations I=Q/t and Q=Ixt, where current equals charge divided by time and charge equals current multiplied by time.

1. Electrical Analogy, Current and Charge
Circuts, electrons
Current goes from +ve to –ve
Current (I) Amps (A)
Time (t) Seconds (s)
Charge (Q) Coulomb (C)
I=Q/T
Q=Ixt
Way to remember:
If you don’t know the equation, you should “Quit”
