Question

With reference to the circuit shown in figure, the current maintained in the circuit will be.

• A. 1.5A
• B. 2.5A
• C. 1A
• D. 5A

Answer 1

The correct option is A 1.5A

Alright. You can solve this question by applying series cells formula.
E = 20-5 = 15V (Since the cells are connected in opposite manner.)
R = 4+6 = 10 $\Omega$
So,
$i=\frac{E}{R}=1.5A$
