Home » Ohm's Law » 9 » b 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. reduced to zero Your answer "b" is CORRECT! I = E / R so to halve the current, just halve the voltage. Next |
