charge
current x time
1 of 8
coulomb
total charge supplies by a current of one ampere in a time of one second
2 of 8
Kirchhoffs first law
the sum of the currents enetering any junction is always equal to the sum of the currents leaving the junction
3 of 8
Electromotive force
the energy transfered per unit charge when one other type of energy is converted into electrical energy
4 of 8
Potential difference
the electrical energy transfered per unit charge when electrical energy is converted into another form of energy
5 of 8
ohm's law
the current through a conductor is proportional to the potential difference across it, provided that physical conditions remain constant
6 of 8
power
rate of work done
7 of 8
Kilowatt-hour
1000 watts for 3600 seconds therefore 3,600,000 J
