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
