Topic 2: Electricity Equations Flashcards
1
Q
What is the charge flow equation?
A
Charge flow = current x time
Q = I x t
2
Q
What is the potential difference equation?
A
Potential difference = current x resistance
V = I x R
3
Q
What is the 1st power equation?
A
Power = current x potential difference
4
Q
What is the 2nd power equation?
A
Power = current (squared) x resistance
P = I (squared) x R
5
Q
What is the 1st energy transferred equation?
A
Energy transferred = power x time
E = P x t
6
Q
What is the 2nd energy transferred equation?
A
Energy transferred = charge flow x potential difference
E = Q x V
7
Q
What is the total resistance equation?
A
Total resistance = resistance of component 1 + resistance of component 2
Rt = R1 + R2
