Question: SSB has an advantage over AM with respect to efficiency and power gain. Why, then, is AM commercial broadcast being replaced with SSB transmission?
Can you help me out on this problem I am got stuck.
Suppose that the machining operation requires 1 kW, that the tool machine ihas 90 percent efficiency, and that the supply current is 14 A rms with a power factor of 0.8. Find the AC machine efficiency.
A Whetstone bridge has a strain gage in the lower right leg with a 120 ohm nominal resistance. It is mounted on steel with a Modulus of Elasticity equal to 30x106. The other resistors are equal to 100 ohms. The bridge voltage is 5V.
What happens when you have a non-zener and zener diode in series opposing each other eg non-zener is forward bias and the zener is reverse bias assuming both are ideal (infinite slopes when they are operating).
The simple inexpensive hydro turbo-generator (turbine mated with electric generator) that you intend to buy has a working efficiency of 60%. Answer the following (show your work).
