Question

the resistance of a 100v bulb is 500 , calculated its current and pawer?

Answer 1

I=V/R
I = 100/500
I = 0.2 Ampere
P=V²/R
P= 100²/500
P= 10000/500
P= 20 Watt
please follow me

Answer 2

Resistance (R) = 500 ohm

Voltage (V) = 100 V

So,

1. Current ( I ) = V / R = 100 / 500 = 0.2 Ampere......●

2. Power ( P ) = V × I = 100 × 0.2 = 20 Watt.....●
