Question

With reference to the circuit as shown in figure, what is the current maintained?

• A. 1.5A
• B. 15A
• C. 0.67A
• D. 6.67A

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,
$i=\frac{E}{R}=1.5A$
