Question

The primary winding of an ideal transformer has $1000$ turns whereas its secondary has $5000$ turns the primary is connected to an ac supply of $220v$ $50Hz$ the secondary will have an output of ____.

Answer 1

Step 1: Given parameters

The number of turns in the primary winding is $N_p=1000$

The number of turns in the secondary winding is $N_s=5000$

The voltage in the primary winding is $V_p=220V$

Step 2: Calculation of voltage in the secondary winding

The voltage in the secondary winding can be calculated as follows:

$\frac{N_s}{N_p}=\frac{V_s}{V_p}$

$\frac{5000}{1000}=\frac{V_s}{220}$

$$\begin{gathered} V_s=\frac{5000}{1000}\times 220 \\ =1100V \end{gathered}$$

The voltage in the secondary winding is $1100V$
