Question

Choose the correct statement(s).

i. The metal disc of an electric cell is a negative terminal.
ii. In electric cell, electrical energy is converted into chemical energy.
iii. Electric current does not flow in an open electric circuit.

• A. i and ii only
• B. only iii
• C. i and iii only
• D. ii and iii only

Answer 1

The correct option is C i and iii only

• The metal cap is the positive terminal of the electric cell and the metal disc is the negative terminal. All electric cells have two terminals; a positive terminal and a negative terminal.
• An electrical cell internally converts the stored chemical energy into the electrical energy.
• Electric current flows in the circuit only if the circuit is closed. If the circuit is open/break no current will flow in the circuit.

Thus, statements i and iii are correct.
