Solution and Explanation
(i) Symbol of a Battery (or Cell):
The symbol \( + \, - \) represents a simple electric cell or battery in a circuit.
- 2Function:2 The function of a battery is to supply electrical energy to the circuit. It provides the voltage or potential difference that drives the current through the circuit.
(ii) Symbol of a Resistor:
The symbol \( \, \bigtriangleup \, \) represents a resistor in an electric circuit.
- 2Function:2 The function of a resistor is to limit or control the flow of electric current in the circuit. It converts electrical energy into heat energy and helps in regulating the current in various parts of the circuit.
