Question

Calculate the work done in moving a charger of 5 coulomb's from a point at 20 v to another at 30 v.

Answer 1

Answer:

v=20v and 30v

V=30-20=10v(since,electric potential changed one point to another)

we have,

q=5c

now,

we know

v=w/q

10=w/5

w=50J

Answer 2

Explanation:

the ampere is a measure of the amount of electric charge passing a point in an electric circuit per unit time with 6.241 × 1018 electrons, or one coulomb per second constituting one ampere
