The voltage is increased by a factor of 4.
The voltage is halved.
The voltage is halved.
To determine what happens to the voltage in a circuit when the resistance is halved, we can analyze Ohm's Law: V = IR.
In this equation, V represents the voltage, I represents the current flowing through the circuit, and R represents the resistance.
If the resistance (R) is halved, the equation becomes V = (I/2)(R/2), which simplifies to V = (IR/4). Therefore, we can see that when the resistance is halved, the voltage is also halved.
So, in answer to the question, when the resistance in a circuit is halved, the voltage is halved as well.
