Question

Find the resistance of the lamp if an electrical bulb is rated 60W,240v.​

Answer 1

960 Ω

Step-by-step explanation:

Answer 2

`R= 960 \: Ohm`

Step-by-step explanation:

P = 60 W

V = 240 V

`P= VI`

`\implies I= (P)/(V)`

`\implies I= (60)/(240)`

`\implies I= 0.25 A`

Now, by Ohms law

`R= (V)/(I)`

`\implies R= (240)/(0.25)`

`\implies R= 960 \: Ohm`
