Question

220
Thus, Current, I = 0.18 ampere
Sample Problem 2. An electric bulb is rated 220 V and 100 W. When it is operated on
the power consumed will be:
(a) 100 W (6) 75 W (c) 50 W (d) 25 W
(NCEKT Book on
Solution. In the first case:
Power, P = 100 W
Potential difference. V = 220 V
And Resistance, R = ? (To be calculated)​

Answer 1

Answer:power consumption will be of 100 w

In the second case resistance will be of 484ohms

Explanation:

1 case formula P= VI

2 case formula P=V2÷R

Answer 2

Power consumption will be of 100 w

In the second case resistance will be of 484ohms

Explanation:

1 case formula P= VI

2 case formula P=V2÷R
