A resistance of 20 ohms has a current of 2 amperes flowing in it. What potential difference is there between its ends?

Academic Physics NCERT Class 10

Given:

R = 20 ohms

I = 2 amp

To find:

the potential difference, V

Solution:

According to ohm's law:

$V=I \times R$

$V=2 \times 20$

$V=40 volt$
