Question

Q4. How much energy is given to two coulomb of charge passing through a 8 volt battery?

Answer 1

Answer:

The energy is given to each coulomb of charge passing through a 8v battery is 8J.

Explanation:

Given that,

q = 1 C

Potential V = 8 v

The energy is given to each coulomb of charge is equal to the amount of work required to move it.

The amount of work is given by the formula of potential difference

V=\dfrac{W}{q}V=

q

W

The work done is

W=V\times qW=V×q ...(I)

Where, W = work done

V = potential difference

q = charge

Put the value of V and q in equation (I)

W=8\times 1W=8×1

W=8\ JW=8 J

Hence, The energy is given to each coulomb of charge passing through a 8 v battery is 8 J.
