Expert Answer
Electric Power Formulas
P = V I
P = R I2
P = V2/ R
where
P = power (Watts)
V = voltage (Volts)
I = current (Amperes)
R = resistance (Ohms)
Electric Current Formulas
I = V / R
I = P / V
Electric Resistance Formulas
R = V / I
R = V2/ P
R = P / I2
Electrical Potential Formulas - Ohms Law
Ohms law can be expressed as:
V = R I
V/I=R
