Question 148: AC fundamentals

Question

Primary coil of a transformer is connected to $$220 \mathrm{~V}$$ ac. Primary and secondary turns of the transforms are 100 and 10 respectively. Secondary coil of transformer is connected to two series resistances shown in figure. The output voltage $$\left(V_0\right)$$ is :

Accepted Answer

$$\begin{aligned}
& \frac{\varepsilon_1}{\varepsilon_2}=\frac{N_1}{N_2}=\frac{100}{10} \Rightarrow \varepsilon_2=22 \mathrm{~V} \
& I=\frac{22}{22 	imes 10^3}=1 \mathrm{~mA}, V_0=7 \mathrm{~V}
\end{aligned}$$
