Question

What changes to be done in the devise to increase the power of the device without changing potential difference

Answer 1

Ways to change Power of a Device :

• Power dissipated from a device refers to the work done by the electrical device in unit time. Mathematically, Power from an electric device is given as Voltage²/Resistance.

$\boxed{ \bf P = \dfrac{{V}^{2} }{R}}$

As per the question, the voltage has to be kept constant !

So, we can say :

$\boxed{ \implies \bf P \propto \dfrac{1}{R}}$

So, we will reduce the resistance of the device in order to increase the power .
