Q
Q: When using a potentiometer, why is it important to keep the circuit closed while taking measurements?
Solution:
Keeping the circuit closed ensures that the current flows properly, allowing for accurate voltage measurements.
Steps: 5
Show Steps
Step 1: Understand what a potentiometer is. It is a device used to measure voltage in a circuit.
Step 2: Know that a circuit needs to be closed for electricity to flow. A closed circuit means all parts are connected.
Step 3: When the circuit is closed, current can flow through the potentiometer.
Step 4: If the circuit is open (not closed), no current flows, and you cannot get a voltage reading.
Step 5: Accurate voltage measurements are only possible when the current is flowing, which happens in a closed circuit.
