resistors (in
parallel) are required to carry 5 A in 220 V line?
Answer:
Here, I = 5A, V = 220 V.
Resistance
required in the circuit, R = 
, Resistance of each resistor, r =
176 
. If n resistors, each of resistance
r, are connected in parallel to get the required resistance R, then R = 
or 44 = 
or n = 
= 4
