In an ideal step-up transformer,if the input voltage and input power are $V_1$ and $P_1$ respectively,and the output voltage and output power are $V_2$ and $P_2$ respectively,then

In a step-up transformer,the turn ratio is $8:1$. $A$ $60\,Hz, 120\,V$ input is connected to its primary coil. The load resistance in the secondary coil is $10^4\,\Omega$. Find the current in the secondary coil.

Due to which reasons do energy losses occur in an actual transformer?

$A$ generator produces a current of $100 \, A$ at $4000 \, V$. The voltage is stepped up to $2 \times 10^5 \, V$ by a transformer before being sent on a high voltage transmission line of resistance $50 \, \Omega$. The percentage of power loss in the transmission line is (in $\%$)

The primary of a transformer has $100$ turns and operates at $100 \,V - 200 \,W$. The number of turns in the secondary,if the output voltage is $2000 \,V$,is:

$A$ step-up transformer has a transformation ratio of $5:3$. What is the voltage in the secondary coil if the voltage in the primary coil is $60 \, V$ (in $, V$)?
