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

Question 10:

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

Solution:

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

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