Question

Marking on a bulb is $60W,220V$. What does it signify?

• A. The bulb is connected across the $220volts,60joules$ of energy is consumed for every second
• B. The bulb is connected across $220volts,60joules$ of energy is released
• C. $60$ unit of current will flow in the bulb
• D. $220$ unit of current will flow in the bulb

Answer 1

The correct option is A The bulb is connected across the $220volts,60joules$ of energy is consumed for every second

$60W,220V$ means the power of the bulb is $60W$ i.e., $60joules$ of electrical energy is consumed in one second, if it is given a potential difference of $220V$.
