It is given that,
Number of turns in primary coil, 
Number of turns in secondary coil, 
Voltage in primary coil, 
Current in primary coil, 
We have to find the voltage and current in the secondary coli. Firstly calculating the voltage in secondary coil as :
Now, calculating the current present in the secondary coil as :
<em>Hence, this is the required solution.</em>
Answer:
-2.66 kJ
Explanation:
At constant pressure, work done is:
W = -P ΔV
