Question

In the circuit shown, potential difference
between A and B is :
(A)
+4 volt
(B)
- 4 volt
(0)
-4.4 volt
(D)
+ 4.4 volt​

Answer 1

Answer:

+4 volt

Explanation:

Because A and B are actually the two terminals (terminal points or ends) of the electric cell itself within which a resistor of resistance of 4 ohm is present.

Thus potential difference between the two terminals "A" and "B" of the cell = 4 V (cleared from diagram) where a resistance of 4 ohm is present in between those two terminals"A" and "B"

My picture will show you the actual diagram of the cell which is required to solve this question. A and B are the two terminals of the cell. In between A and B, a resistance of 4 ohm is present.
