A resistor has a resistance of 176 ohms. How many of these resistors should be connected in parallel so that their combination draws a current of 5 amperes from a 220 volt supply line?

Given I=5A
P.D.=220V
therefore R=V/I
R=220/5
R=44
Also, R=176 ohm
According to the question,
1/44=1/176(n)
n=176/44
Therefore n=4
Hope it helps u :)
