The energy supplied by the cell to the charge carriers is derived from the conversion of:
Correct answer: B. Chemical energy into Electrical energy
- A. Heat energy into Electrical energy
- B. Chemical energy into Electrical energy
- C. Solar energy into Electrical energy
- D. Mechanical energy into Electrical energy
Explanation
Explanation:The energy supplied by the cell to the charge carriers is derived from the conversion of chemical energy into electrical energy. This option is not correct because a thermoelectric cell converts heat energy into electrical energy.This option is also incorrect because a solar cell converts solar energy into electrical energy. This option is also incorrect because a generator converts mechanical energy into electrical energy.

About Steady Current
Steady current is the continuous flow of charge at a constant rate through a conductor. The topic covers current, charge, potential difference, resistance, Ohm's law, resistivity and electrical power, along with series and parallel circuits, while distinguishing conventional current direction from electron motion.
