Question 393: Current Electricity

Question

In the given figure an ammeter A consists of a $$240 \Omega$$ coil connected in parallel to a $$10 \Omega$$ shunt. The reading of the ammeter is ________ $$\mathrm{mA}$$.

Accepted Answer

$$\begin{aligned}
& i=\frac{24}{140 \cdot 4+r_A}=\frac{24}{140 \cdot 4+9 \cdot 6}=0.16 \mathrm{~A} \
& i=160 \mathrm{~mA}
\end{aligned}$$
