Question

why we add two potential differences when it is told to calculate the TOTAL POTENTIAL DIFFERENCE​

Answer 1

Answer:

total potential difference :-

means sum of all potentials . so add them.

total = add

Answer 2

TOTAL POTENTIAL DIFFERENCE means the sum total of all potential differences.

Let there are four potential differences, 4 Volt, 5 Volt, 6 Volt and 10 Volt

Then, total potential difference = net potential difference = (4+5+6+10) volt = 25 volt
