what is the need to express current and voltage in rms value? rms value is also called as effective value,what is effective value?
Bhel,
1903what is mean by kneepoint voltage? when it will happen? ( my doubt is, if CT secondary is open means ct get saturation or blas? what are factors are required for calculations? plz give currect anws:

Explain the basic circuits for a current- and voltage- clamp set-up.
What types of I/O have you designed? What were their size? Speed? Configuration? Voltage requirements?
I just want to convert the voltage into current i.e. suppose I have 750V & 1A AC power then I want to convert it into 12V & 62A DC power only difficulty is that I don't want to use the tranceformer. Simply to say, I want to make the step-down without using tranceformer. Please, give me some ideas. And also I want the relation between Magnetic Induction & Weight of the body can be levitated. Or I can say, how much of magnetic induction requires to lift 500gms weight? I am heartily thankful to you.
iam using DM 3251 voltmeter(1 percent accuracy)for 11KV system PT ratio is 11KV/110V.can anybody explain what is the max and min voltage deviation.
how define the torque in ac drive. from electrical side in the drive friquency ,voltage and current three factor is there.
can we calculate the voltage level for microwave energy which is using for our mobile communication?
Is it possible to calculate a voltage for microwave energy generating in oven? Is there any formula relating frequency and voltage and it should be independent of speed?
Formulae for calculating the transmission line losses for different voltage levels
