<div>a resistor has a resistance of 176 ohms . how many of these resistors should be connectd in parallel so that their combinations draws a current of 5 ampere from a 220 volt supply line?</div>

Given that the resistors are connected in parallel. That is,
So, RP = (176/x) Ω
The equivalent resistance of the resistors connected in parallel is given by Ohm’s law as VIR
Where, V= 220 V and Current, I = 5 A
220 V = 5 A × (176/x)
On solving, we get
x = 4
Four resistors should be connected in parallel.
