Question

8.
Potential difference between the points P and Q in the electric circuit is
i=1.5A
(1) 4.5V
(2) 1.2 V
(3) 2.4 V
(4) 2.88 V
​

Answer 1

Answer:

Explanation:

Current between P and Q; i = 1.5A  (Given)

The potential difference is the difference of electrical potential between two points. The amount of work done known as(W) by bringing a unit positive charge as (Q) from one point to the another point is called electric potential difference. with the SI unit as Voltage(V).

Equivalent resistance between P and Q

1/ Rpq = 1/ ( 6+2) + 1/3 + 1 ( 4 + 12)

= Rpq = 48/25

Thus, the potential difference between P and Q will be -

Vpq = 1.5 × 48/25

Vpq = 2.88 V

Thus, the potential difference will be 2.88V.
