| Assertion (A): Electric appliance with metal body has three electrical connections. But an electrical bulb has two electrical connection. |
| Reason (R): Three pin connection reduces chances of electrical shocks. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is true
Correct Answer: A
Solution :
| Option [a] is correct |
| Explanation: The metallic body of electrical appliance is connected to the 3rd pin which is an earth pin. |
| By any chance if the metallic body gets connected to the LIVE line, current flows to earth through this pin without giving any shock to the user. |
| Hence assertion is true. |
| Electric bulb does not have any metallic encloser and hence there is no requirement of earth pin. So, the reason is also true and properly explains the assertion. |
