The parallel combination of a 470
resistor and a 1.5 k
resistor is in series with the parallel combination of five 1 k
resistors. The source voltage is 50 V. The percentage of the load current through any single 1 k
resistor is

Five 1k ohm parrallel R=200..
i =V/R =50/200=0.25.
i for 1k, i = 50/1000 = 1/20 = 0.05.
i %=0.05 * 100/0.25 = 20%.
i =V/R =50/200=0.25.
i for 1k, i = 50/1000 = 1/20 = 0.05.
i %=0.05 * 100/0.25 = 20%.

You are right @Shashank.
But can you tell me what is the formula if there is not same resistance in parallel?

@Priya,
Where does that 1/4 comes from I am not getting that?

Actually, they ask for a percentage. So, for 51K ohms resistor 50V/200ohm = 0.25A.
Again 50/1 Kohm = 0.05A, therefore 0.05/0.25*100 = 20%.
Again 50/1 Kohm = 0.05A, therefore 0.05/0.25*100 = 20%.

Of course @Meena you are right.
But this simple and quick method is only applied when all the resistors are of same value. Otherwise you can't applied when resistors are of different values are given.
What is the simple method when resistors are of different values are given?
