Question

How many resistors of 440 ohm connected in parallel would give equivalent resistamce of 44 ohm

Answer 1

Equvalent resistance = $\frac{R}{n}$

Where R = resistance of one resistor and n ie number of resistors.

44 ohm = $\frac{440}{n}$

By transposition,

n = $\frac{440}{44}$

n = 10

So 10 resistors of 440 ohm are required to connect in parallel to give equivalent resistance of 44 ohm
