Calculate the work done charge of 25 coulombs across 2 points with a potential difference of 20 v |
|
Answer» Charge (Q) = 25 C Potential Difference (V) = 20vTo Find:-Work done (W) Solution:-As we know that Potential difference between two point = work done/charge→ P = W/QSubstitute the value we get→ 20 = W/25→ W = 25 ×20→ W = 500 Joule.Extra Information !!Potential Difference: The potential difference between two point in an electric circuit carrying some current as the work done to move a UNIT charge from one point to the other.Potential difference = Work done /Charge.V = W/Qhere V is the potential differenceW is the work doneQ is the charge ✧ SI unit of electric potential energy is volt (V).✧ 1 volt : The potential difference between two points in a current carrying conductor when one joule of work is done to move a charge of one coulomb from one point to other.1 Volt = 1Joule/1Coulomb |
