- The vaule of resistance of resistor having a 31 Voltage and current of 21 Amplere is ohm.Use a variation model to solve for the unknown value. The current in a wire varies directly as the voltage and inversely as the resistance. If the current is 12 amperes (A) when the voltage is 80 volts (v) and the resistance is 10 ohms (2), find the current when the voltage is 150 V and the resistance is 12 2. The current is A when the voltage is 150 v and the resistance is 12 n. (Round to two decimal places, if necessary.)Three resistors A, B and C are connected in series to a 120-V supply. If the resistor A = 50 Ω and the voltage across B, VB = 40 V when the current is ½ A, what is the resistance of resistor C in ohms?
