What happens to the circuit if the voltage was doubled for each step but the resistance was halved the current would 1- increase by twice as much 2- decrease by one-half 3- decrease by one-fourth 4-in?

If the voltage is doubled and the resistance is halved, according to Ohm's Law (V = IR), the current would actually increase by four times. Doubling the voltage increases the driving force for the current, while halving the resistance decreases the opposition to the current flow. Therefore, the correct outcome is that the current would increase by four times, not one of the options provided.
