Question

How many resistors of 2000 each are required in parallel
combination, so as to carry SA on a 200V line supply?​

Answer 1

Answer:

Q 10: How many 176 Ω resistors (in parallel) are required to carry 5 A on a 220 V line?

Ans: 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.
