Home » Ohm's Law » 9 » d A current of 0.5 ampere flows through a resistance when 6 volt is applied. To change the current to 0.25 ampere the voltage must be: a. increased to 12 volt b. reduced to 3 volt c. held constant d. Your answer "d" is not correct. "b" is the right answer. I = E / R so to halve the current, just halve the voltage. Next |
