請大大們教我算這一題
感激不盡

A transformer-coupled class A amplifer drives a 16 ohm speaker through a 3.87:1 transformer.

Using a power supply of vcc=36v,the circuit delivers 2w to the load.

calculate:

a.P(ac) across transformer primary.

b.VL(ac).

c.V(ac) at transformer primary.

d.the rms values of load and primary current.
