Electric Current

A magnet spinning around a conducting wire creates an ekectrical current.

Electric Current is the rate of the flow of charged particles past a point.

For our example, we will have electrons moving through a wire.

V=IR

V= Voltage (volts)

I= Current (amperes)

R= Resistence (ohms)

Electric current has the unit, ampere, and one ampere is one Coulomb per second.

1 Volt = 1 \dfrac {Joule}{Coulomb}

1 Ampere = 1 \dfrac {Coulomb} {second}
