. If the current I through a resistor is increased by
100% (assume that temperature remains
unchanged), the increase in power dissipated will be
(a) 100 % (b) 200 %
(c) 300 % (d) 400 %
pls give me solution
NO SPAM PLEASE......
I WILL MARK IT As BRANisT

Answer:
Let the original value of current is I ampere.
The new value of current I′=I+100%I=2I.
Now, the new power P′=I′2
R=4I
R=4P.
So, the change in power = P′−P=3P
Therefore, the change in power in terms of percentage is 300%.
Hence, the increase in power dissipated will be 300%.
