Question

An electric device of 20 ohms had
done a work of 1000 Joules.
with potential difference asv.
Find the Current in the Circuit
& charges flowing through it​

Answer 1

Answer:

Explanation:

Therefore;

Voltage

=

Work done

Charge

Voltage or electric potential difference is denoted by ‘V’. Therefore;

V

=

W

Q

-----------(1)

Where, W = work done and Q = Charge

SI unit of electric potential difference (Voltage):

SI unit of electric potential difference is volt and denoted by ‘V’. This is named in honour of Italian Physicist Alessandro Volta.

V

=

Joule

Or,  

V

=

Since joule is the unit of work and coulomb is the unit of charge; 1 volt of electric potential difference is equal to the 1 joule of work to be done to move a charge of 1 coulomb from one point to another in an electric circuit. Therefore,
