ELECTRICITY equations Flashcards
1
Q
charge flow
A
charge flow= current × time
2
Q
potential difference
A
potential difference = current × resistance
3
Q
total resistance
A
total resistance = resistance of component 1 +
resistance of component 2
4
Q
power (with potential difference)
A
power= current × potential difference
5
Q
power (resistance)
A
power = (current)2
× resistance
6
Q
energy transferred (with power)
A
energy transferred = power × time
7
Q
energy transferred (with p.d.)
A
energy transferred = charge flow ×
potential difference �
