A portable x$-$ray unit requires a step$-$up transformer, the $120-$V input of which is transformed to

the $10-$ kV output needed by the x$-$ray tube. The primary has $50$ loops and draws a current of $10$ A

when in use.

a$)$ What is the number of loops in the secondary coil? $(8$ Points$)$

b$)$ What is the current output of the secondary$?(8$ Points$)$

c$)$ Do your answers satisfy the Law of conservation of Energy, i$.$e$.$ does Power input $=$ Power

output?
