When a pot difference of 4 volt is applied across resistance, 10 J of energy is converted. Findcharge flows
Correct answer: B. 2.5 C
- A. 0.20 C
- B. 2.5 C
- C. 5.0 C
- D. 10.0 C
Explanation
When a 4-volt potential difference is applied across a resistor, causing 10 joules of energy to be converted, 2.5 coulombs of charge flow through the resistor.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
