Comment on Frankenstein power supply

Hi. I've attached a circuit diagram. The schematic is for a dc power supply. It's purpose it to charge nicad batteries. However, we are having trouble locating the transformer. The transformer has been omitted, and the power is just represented by an AC power source. I'm a little unclear about the C-L-C portion of the ...continues

Two power sources in a circuit

I need to find the voltmeter reading and how to deal with 2 power sources Is this going into Thevenins or kirchoffs?

Derive rationalised admittance expressions

This question is part of my revision guide, it is worth 15 marks, I am unsure of what the question is asking me to do. Could you please derive the expression in detail and show me why it would be worth so many marks as a question.

resonance

I have attempted this revision question although I am not convinced that my answers are correct. I believe the Res Freq is 9.19KHz is this correct? Can you please show me how to complete this question and the formula required to do so.

lightbulb resistance and efficiency

A GE Softwhite lightbulb is rated as follows: rated power = 60 W ; rated optical power = 820 lumens (lm) 1 lm = 1/680 W operating life = 1.5 h rated operating voltage = 115 V The resistance of the filament of the bulb, measured with a standard multimeter is 16.7 ohms. When the bulb is connected into a circuit and is ...continues
