Solution

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
