Question

If the current I through a resistor is increased by
100 % (assume that temperature remains
unchanged), the increase in power dissipated will
be (in %)​

Answer 1

your answer mate

Brother

assume if you have a constant voltage V and you have to increase current I. Then, what would you do is to reduce resistance R. Then only would you be able to increase current.

And by the way, voltage is not directly proportional to current, CURRENT IS DIRECTLY PROPORTIONAL TO VOLTAGE.

If you change current, voltage WILL NOT change but if you change voltage, then, current WILL CHANGE.

Answer 2

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%.
