Question

Determine the current flowing through the circuit shown above.

• A. 25 mA
• B. 12.5 mA
• C. 29 mA
• D. 80 mA

Answer 1

The correct option is B 12.5 mA

Using Kirchoff's law, If I is the current flowing through circuit, then:
$(3-0.5V)+(I\times 200)=0$

$\Rightarrow I=\frac{2.5V}{200}=12.5\times {10}^{-3}A$

$=12.5mA$
