Question

- How many 176 a resistor (in parallel) are required to carry 5 A on a 220
V line ?​

Answer 1

Answer:

Explanation: 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

From Ohm’s law,

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