Question

calculate the current and the resistance of 100w.200v electric bulb in an electric circuit​

Answer 1

Answer:

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:

Explanation:

Power = V^2/R

Given, P = 100 W

V = 200

R = V^2/P

R = (200)^2/100

R = 400 ohm

Now Current ,I = V/R

I = 200/400

I = 1/2 = 0.5 A
