Alternating Current Question 8
Question 8 - 2024 (30 Jan Shift 1)
Primary coil of a transformer is connected to $220 V$ ac. Primary and secondary turns of the transforms are 100 and 10 respectively. Secondary coil of transformer is connected to two series resistance shown in shown in figure. The output voltage $\left(V _0\right)$ is :
(1) $7 V$
(2) $15 V$
(3) $44 V$
(4) $22 V$
Show Answer
Answer: (1)
Solution:
$\frac{\varepsilon _1}{\varepsilon _2}=\frac{N _1}{N _2}=\frac{100}{10} \Rightarrow \varepsilon _2=22 V$
$I=\frac{22}{22 \times 10^{3}}=1 mA, V _0=7 V$
