Question

If power is 100 and voltage is 220 then what will be the resistance?

Answer 1

As u know p is equal to I into r therefore r is equal to I upon p

100/220 = 0.45

HOPE THAT HELPS YOU.....

Answer 2

Given:

Power = 100w

Voltage = 220

Formula for Resistance = Voltage/Current

Formula for current = Power / Voltage

                                 = 100/220 = 0.4545 A

Resistance = 220/0.4545 = 484.0484 ohm
