. How many 176 resistors in parallel are required to carry 5 A on a 220 V line
Answer: Here, Potential difference = is 220 V
And the current, I = 5 A.
Thus, the resistance of the circuit is 44 ohms.
Now, we need to find the number of resistors should be connected in parallel to obtain a resultant resistance of 44 . Suppose the number of 176 resistors required is ‘n’.
Thus, 4 resistors of 176 each should be connected in parallel.
