Question

An tube of 100 Ω, Iron of resistance 50 Ω, and refrigerater of resistance 500

Ω are connected in parallel to a 220 V source. What is the resistance of an

electric iron connected to the same source that takes as much current as all

three appliances, and what is the current through it​

Answer 1

Answer:

Total R=125/4 ohms =31.25

i in 100 ohm tube = 2.2A

I in 50 ohm iron =4.4 A

I in 500 ohm refrejerator= 0.44 ohm
