Question

Guys help me to solve out this one problem !
A electric iron draws a current of 3.4Ampere from the 220V line .what current will iron draw when connected to 110V supply line ??

Answer 1

Answer:

εηηο!❤

____________❤your answer is Current =>1.7Ampere

__________________❤

V/I=R

220/3.4= 64.7

R=64.7Ω

________________

Now,second case

_________________

V/I=R

110/I=>64.7

I=>110/64.7

I=>1.7Ampere

Answer 2

I= 3.4 Amp

V= 220 Volts

Electric iron has a resistance = R

V = I R

= R = V/I = 220/3.4

= 64.7

When the electric iron is connected to a 110 Volts supply,

I = V/R = 110/64.7= 17 Amp.

===================

Alternately,A the voltage becomes half of its value ,the current becomes half of its value,as the current is directly proportional to the potential difference

across a conductor or resistor.This is as per Ohm's law.
