An electric bulb of 500 watt at 100 volt is used in a circuit having a 200 V supply. Calculate the resistance R to be connected in series with the bulb so that the power delivered by the bulb is 500 W.
Multiple Choice Options
- A 20 Ω
- B 30 Ω
- C 5 Ω
- D 10 Ω
Step-by-Step Verified Solution
500 watt at 100 v
P = Vi
500 = Vi
i = 5 Amp
V = i
R = 20
P = Vi
500 = Vi
i = 5 Amp
V = i
R = 20
