A resistor has a

Answer :

We Know according to Ohms Law that:-
V= IR
Where V= Voltage/Potential Difference
I= Current
R=Resistance
According to Question :-V= 220V
I= 5A
∴ Total Resistance of the Combination is :-
Suppose x resistors should be connected in parallel to draw a current of 5A

for parallel combination:-

1/R = 1/R1 +1/R2+ 1/R3........1/RX(Where Resistance of each Resistor is 176Ω)

According to the question,

RCombination=176/x
⇒44=176/x( We know from above the total resistance of combination)

x=176/44=4 resistor
Hence 4 resistors each of 176Ω should be connected in parallel so as to draw the current of 5A from a 220 volt supply line.
