Questions & Step-by-Step Solutions
If the length of the potentiometer wire is increased, what effect does it have on the maximum measurable voltage?
Step 1: Understand what a potentiometer is. It is a device used to measure voltage by comparing it to a known voltage.
Step 2: Know that the potentiometer wire has a certain length and this length affects how much voltage it can measure.
Step 3: Realize that when you increase the length of the wire, you are also increasing the area over which the voltage can be measured.
Step 4: Understand that a longer wire means a larger potential gradient, which is the change in voltage per unit length of the wire.
Step 5: Conclude that with a larger potential gradient, the potentiometer can measure a higher maximum voltage.
Potentiometer Functionality – A potentiometer measures voltage by balancing it against a known reference voltage, and its effectiveness is influenced by the length of the wire, which affects the potential gradient.
Potential Gradient – The potential gradient is the change in voltage per unit length of the wire; a longer wire allows for a greater range of measurable voltages.
