Question

a heater of tlresistance 50 ohm is connected to 220v line how much cureent will this heater draw

Answer 1

according to ohms law
V= IR
here
V= 220 V
R= 50 ohm
V= IR
220= I*50
220/50=I
I= 4.4 ohm

Answer 2

From ohms law we have
V= IR

where
V= 220v
R = 50 ohm
I = ?

220 = l (50)

l = 220/50

= 4.4A
