# 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?

Expert Answer:

### Given that the resistors are connected in parallel. That is,
So, R_{P }= (176/x) Ω
The equivalent resistance of the resistors connected in parallel is given by Ohm’s law as *V*= *IR*

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.

_{P }= (176/x) Ω

*V*=

*IR*

Where,

*V*= 220

*V and*Current,

*I*= 5 A

220 V = 5 A × (176/x)
