Explanation:
you have connected all the appliances in parallel.
so,
1/equivalent R = 1/R + 1/R² + 1/R³
R¹ = 100 ohm
R² = 50 ohm
R³ = 500 ohm
1/equivalent = 1/100+1/50+1/500
= 5/500+10/500+1/500
=16/500
equivalent R = 500/16
= 250/8
=125/4
by ohms law,
V=IR
220 = I×125/4
I = 220×4/125
I = 44×4/25
let the resistance of electric iron be r
v=ir
220 = 176/25 ×r
220×25/176 = r
31.25 ohm is the resistance of the electric iron.
current = 7.04 amperes
hope this helps!
