MCQ
What is the driving force in a working Electrical Circuit?
- ✓Voltage Difference.
- BCurrent.
- CTemperature difference.
- DChemical Imbalance.
✓
Answer
Correct option: A.
Voltage Difference.
When a potential difference is applied across a resistor then randomly moving free electrons start to move towards positive terminal due to force applied by electric field generated due to voltage difference. thus a start to Current Flows from High Voltage to Low Voltage.
Voltage is cause and current is effect.
