Electricity Flashcards
1
Q
charge flow =
A
charge flow = current x time
2
Q
potential difference =
A
potential difference = current x resistance
3
Q
IN A SERIES CIRCUIT
total resistance
total potential differnece
total current
A
Rtotal = R1 + R2
potential difference is shared between components
current is the same through each component
4
Q
IN A PARALLEL CIRCUIT
potential difference
current
A
potential difference is the same across each component
total current through the circuit is the sum of currents through each component
5
Q
power = (2 equations)
A
power = potential difference x current
power = (current)^2 x resistance
6
Q
energy transferred =
2 equations
A
energy transferred = power x time
energy transferred = charge flow x potential difference
