Equations for electricity Flashcards
1
Q
charge flow
A
charge flow= current x time
Q = It
2
Q
potential difference
A
potential difference= current x resistance
V = IR
3
Q
total resistance
A
total resistance= resistance of component 1 + resistance of component 2
R(small)T=R1+R2
4
Q
power
A
power = current x potential difference
P = IV
power = (current)^2 x resistance
P = I^2 x R
5
Q
energy transferred
A
energy transferred = power x time
E = Pt
energy transferred = charge flow x potential difference
E = QV
