How many \(176\ Ω\) resistors (in parallel) are required to carry \(5\ A\) on a \(220\ V\) line?

Number of required resistors \(=\ x\)

The equivalent resistance of the parallel combination of resistor \(R\) is given by

R = \frac{i}{i}

From the Ohm's law,

i = i \times i

, the formula for resistance can be found.

i = \frac{i}{i}

On substituting the known values, we get the number of required resistors as .
