Answer 2

Answer:

For x number of resistors of resistance 176 Ω,

Here Supply voltage, V = 220 V

Current, I = 5 A

Equivalent resistance of the combination = R, given as

I/R = X x (1/176)

R = 1 /176

From Ohm’s law,

V/I = 176 /X

X = 176 x I / V

   = 176 x 5 /220

   = 4

∴four resistors of 176 Ω are required to draw the given amount of current.
