Question
As the voltage increases, the number of electrons passing through the circuit is affected. What is the effect on the resistance in the circuit?
- Resistance increases
- Resistance decreases
- Resistance remains same
- Cannot say
Hint:
Ohm's law describes the relation between voltage, current, and resistance.
The correct answer is: Resistance remains same
According to the Ohm's law, current in the circuit is directly proportional to the voltage.
If the voltage in the circuit increases, current will also increases and resistance will be same.
