Q
Q: What is the effect of increasing the resistance in the circuit of a potentiometer?
Solution:
Increasing the resistance in the circuit decreases the current according to Ohm's law.
Steps: 5
Show Steps
Step 1: Understand what a potentiometer is. It is a device that can change resistance in a circuit.
Step 2: Know that resistance is a measure of how much a material opposes the flow of electric current.
Step 3: Remember Ohm's Law, which states that Voltage (V) = Current (I) x Resistance (R).
Step 4: If you increase the resistance (R) in the circuit, and the voltage (V) stays the same, the current (I) must decrease.
Step 5: This means that with higher resistance, less current flows through the circuit.
