Question

If power is 100 watt and voltage is 220. Find its resistance.
(A) 2.5
(B) 3.5
(C) 4.5 hp
(D) 5.5​

Answer 1

Answer:

bro options are wrong

Step-by-step explanation:

but the right answer is 484 ohm

ok

Answer 2

Answer:

As you know that power = v² / resistance

So, 100 = 220×220 / resistance

=> Resistance = 220×220/100

=> Resistance = 22×22 = 484 Ohm
