1.       Equivalent Resistance between X & Y

2.        Two 230v, 'x' watts power wire are connected in parallel & it is used to heat water when the same is connected in series at same temp what is ratio of time taken by the two.

3.       Transformer turns ratio is 1:4 if primary resistance = 25ohms secondary resistance =?

4.        Capacitive Reactance = 40 ohms Frequency = 500hz If the freq is reduced to 100hz what is the value of resistance.

5.       If the resistance of wire of diameter 'D' & length 'L' is 'R' then the resistance of same wire of diameter 4D & length 16L is what?
