Question

define 1 volt. express it in term of s.i unit of work and charge. calculate the amount of energy consumed in charging a charge of 1 columb through a battery of 3 volt...

Answer 1

If 1 joule of work is done to carry 1 coulomb of charge from one point to another point , then it is said to be 1 V

Since we know that V=W/Q
so, put V = 3V And Q=1 c
by equating this in formula we get 3 j

I hope it is helpful to you...

Answer 2

Definition of 1 Volt :

• 1 Volt is defined as the 1 Joule of work done to transport 1 Coulomb of positive charge through a uniform electric field from one point to another.

In other words, 1 Volt = 1 Joule/1 Coulomb.

Now, charge of 1 Coulomb is given through a battery of 3 Volts. So, the work be W (let).

$\therefore \: V = \dfrac{W}{q}$

$\implies \: W = V \times q$

$\implies \: W = 3 \times 1$

$\implies \: W = 3 \: joule$

So, 3 Joule of work is done .
