Question

that zero Watt lamp is in fact A 15 Watt lamp True or false
​

Answer 1

Explanation:

The ''zero watt'' lamp is, in fact, a 15-watt lamp. Conventional electro-magnetic energy meters did not record consumption if the load was very small. The indicator did not move when the load was only 15 watts when at night there was no other electrical load except the ''zero watt'' lamp.
