Question

Calculate the current and resistance of a 100 W, 200V electric bulb.​

Answer 1

Explanation:

Hy here is ur answer:-

Here, Power of the bulb = 100W

Voltage=200V

so, Current I = P/V=100/200=1/2 = 0.5 A

So, resistance=V/I=200/0.5=400 ohm

Answer 2

Answer:

Power (P) = 100 W

Voltage (V) = 200 V

Power (P) = VI

Therefore , Current (I) = P/V

= 100/20

= 0.5 A

Resistance (R) = 200/0.5

= 400 ohm
