Question

2. How many 174 ohm resistors (in parallel) are
required to carry 5A on 220V line ​

Answer 1

Answer:

For 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.
