Question

An electric iron draws a current of 3.4 a from the to 220 volt supply line what current will this electric iron draw when connected to 110 volt supply line

Answer 1

Answer:

1.7 A

because

220/3.4=110/x

so x=1.7

Answer 2

Explanation:

say the current is ii when connected to 110V110V supply, setup a proportion using ohm's law and solve ii

\dfrac{3.4}{220}=\dfrac{i}{110}2203.4=110i

i=1.7Ai=1.7A
