# The voltage needed to produce a current of 12 A in a resistance of 20 ohms is?

a. 240 V

b. 0.6 V

c. 8 V

d. 1.67 V

a...240V

according to equation V=I*R voltage needed to produce is

a. 240 V

Voltage = current x Resistance

therefore, 240V

240v

V=IR or voltage=current(in Amps) times resistance(in Ohms)

So 12 Amps X 20 Ohms = 120 Volts

240V

OHM'S Law:

voltage = resistance x current

volts = ohms x amperes

240v = 20 ohms x 12 amperes
