Question

The resistance in a circuit is halved. What happens to the voltage?

V=IR

The voltage remains the same.

The voltage is halved.

The voltage is doubled.
]
The voltage is increased by a factor of 4.

Answer 1

If the resistance in a circuit is halved, the current will double. This is in accordance with Ohm's law, which states that the voltage across an ohmic resistor is directly proportional to the current flowing through it.

Step-by-step explanation:

According to Ohm's law, the voltage across an ohmic resistor is directly proportional to the current flowing through it. Therefore, if the resistance in a circuit is halved, the current will double.

In the equation V = IR, where V is voltage, I is current, and R is resistance, if the resistance is halved, the current has to double in order to maintain the same voltage.
