Name the device used to change the resistance without changing the voltage source in an electric circuit.

*the devices which are used to change the resistance in a circuit are called **resisitors... ** the fact that they effect the voltage or not simply depends upon the type of resistor used in the circuit ...:)

The device used to change resistance without altering the voltage in a circuit is known as a rheostat or potentiometer. Both devices allow for adjusting resistance and are commonly used in applications such as volume control and dimmer switches. They provide flexibility in controlling electric current in various circuits.
