Solution


Electrical circuit showing the connection of various components

The above circuit can be proved by Ohm's law.

Ohm’s law The relationship between the current flowing through a wire (I) and the potential difference across its ends (V) can be obtained from the law that was given by the German scientist George Simon Ohm.
