Question
ABCDE is a pentagon. The potential at A is 12𝑉12V, potential at B is 15𝑉15V, potential at C is −11𝑉−11V, at E it is −17𝑉−17Vand at D the potential is not known. What is the potential drop when you move from B to E?
Solution
The potential drop when moving from one point to another is calculated by subtracting the initial potential from the final potential. In this case, we are moving from point B to point E.
The potential at B is 15V and the potential at E is -17V.
So, the potential drop from B to E is calculated as follows:
Potential drop = Final potential - Initial potential = Potential at E - Potential at B = -17V - 15V = -32V
So, the potential drop when you move from B to E is -32V. This means that the potential decreases by 32V.
