What is the formula for calculating power in an electrical circuit?
P = V × I
P = I ÷ R
P = V ÷ I
P = I × R
How do you calculate voltage using current and resistance?
V = I × R
V = P ÷ I
V = R ÷ I
V = I ÷ R
Which equation represents the calculation of current?
I = P ÷ V
I = V × R
I = V ÷ R
I = P × V
What is the formula for calculating resistance?
R = V ÷ I
R = I × V
R = P ÷ I
R = V × I
