Question

In which of the following case, the flow of electric current will be maximum?

• A. When the potential difference across the device is more
• B. When the potential difference across the device is less
• C. When resistance of the material used is high
• D. When there is no potential difference

Answer 1

The correct option is A

When the potential difference across the device is more

Potential difference is defined as the difference of electrical potential between two points. Potential difference is directly proportional to the current in the circuit. Hence more the potential difference, more will be the current in the circuit and vice versa.
