Question

Electric iron when hot draws 2A current when connected to 220 volt line find the resistance of the coil of the electric iron

Answer 1

current I=2A
p.d /voltage V=220v
let the resistance of the coil =R
From ohm's law,
V=IR
R=V/I
R=220/2
R=110 ohm

Answer 2

current (I) =2 Ampere (A)

voltage (V) =220v

resistance of the coil =R

V=IR

R=V/I

R=220/2

R=110 Ω
