Question

how many resistors of 176 ohm should be connected in parallel to get 5A current from 220V supply?​

Answer 1

Answer:

The correct answer is n = 4.

Explanation:

Let 'n' be the number of resistors that are to be connected in parallel.

Now, Equivalent resistance of this connection is given as:

$\frac{1}{R_{eq} } = \frac{1}{176} + \frac{1}{176} + \frac{1}{176} +......... n times.$

⇒    $R_{eq} = \frac{176}{n}$

Using Ohm's Law  ⇒   220 = 5*176/n

⇒   n = 4

Hope You understand it !!!!!!!!!!!1
