1/R = x(1/176)
R = 176/x
V = ir
220/5 = 176/x
880/220 = x
4 =x
So 4, 176 resistors are needed
1/R = x(1/176)
R = 176/x
V = ir
220/5 = 176/x
880/220 = x
4 =x
So 4, 176 resistors are needed

Let the total no. of resistors = x
Given,
I = 5 A
V = 220 V
According to Ohm’s law,
V = IR
R = V/ I = 220/5 = 44Ω
Now for x number of resistors of resistance 176 Ω, the equivalent resistance of the resistors connected in parallel is 44 Ω.
1/44 = 1/176 + 1/176 + 1/176 .....χ times
1/44 = x / 176
=> x = 176/ 44
=> x = 4
Therefore, 4 resistors of 176 Ω are required to draw the given amount of current.
I hope, this will help you___❤❤
