What is the resistance of the hair dryer?
What is the resistance of the hair dryer? R = (Voltage)/(Current)= 120 V/13 A = 9.2 W. If two resistances are linked together with a single wire as in the diagram, the current through each resistor is the same. The potential drop across each resistor is equal to the current times the resistance of that resistor.

How do you calculate voltage resistance?
From this, we conclude that; Current equals Voltage divided by Resistance (I=V/R), Resistance equals Voltage divided by Current (R=V/I), and Voltage equals Current times Resistance (V=IR).
How do you find resistance with voltage and watts?
For example if the power is 100 watts and the voltage is 50 volts, the current is 100 / 50, or 2 amps. Calculate the resistance, in Ohms, by dividing the voltage by the current. Ohms law states that voltage = current x resistance, so by rearranging the formula resistance = voltage / current.
