Question

Find the Value of Fall in Potential
To determine the sign of e.m.f., the value of fall in potential is: (a) Negative (b) Positive (c) Both negative and positive (d) None of the above

Answer 1

Both negative and positive.....

Answer 2

To determine the sign of EMF the value of fall in potential is both negative and positive. (Option C)

• Gravitational ability power and electric powered ability power are pretty analogous.
• Potential power for paintings is achieved via way of means of conservative pressure and offers introduced perception concerning power and power transformation without the need of coping with the pressure directly.
• It is a lot greater common, for example, to apply the idea of voltage (associated with electric powered ability power) than to cope with the Coulomb pressure directly.
• Thus, to determine the sign of EMF the value of fall in potential is both negative and positive.
