Ohm's law deals with the relation between voltage and current in an ideal conductor. It states that: Potential difference across a conductor is proportional to the current that pass through it. It is expressed as V=IR. Therefore, the correct answer would be option 1. The current will increase as well since there is an increase in the voltage.

When John increases the voltage from 25 volts to 50 volts while keeping the resistance constant, the current will definitely increase in the electric circuit.

What is an Electric circuit?

A circuit is a closed-loop through which electric charge flows as a result of a driving voltage. Current is the rate of flow, measured as the amount of charge passing a given point in the circuit per unit time. Several components such as a battery, resistor, capacitor, bulb, and switch make a complete electric circuit.

If the resistance remains constant, an increase in voltage will surely increase the electric current. By the definition of Ohm's law, V=IR, where voltage (V) is directly proportional to electric current (I), and R is the resistance which is constant.

Therefore, When John increases the voltage from 25 volts to 50 volts while keeping the resistance constant, the current will definitely increase in the electric circuit.
