How do you measure no-load current in a stabilizer?
Measuring No-LoadIn theory the no-load current of a transformer is zero. But in practice there is iron loss and core loss in the transformer, so there is power loss. Connect an ammeter in series with the stabilizer to measure the no-load current. Check your energy meter at no-load to see how much power is consumed. Ohms law: I(Amps) = E(voltage) divided by R(resistance). In the case of coils (transformer), the resistance of the coil would simply be the total impedance (Z). If I am remembering this correctly, you get, I=E/(R+Z)
What are the units of measurement for current load and amperage?
The unit of measure for current load is amperage, or simply amps.
What do you understand by stabilizer explain its uses?
A Stabilizer maintains the voltage across a load constant no matter how high the current goes.It can be used to maintain the voltage across a load constant no matter the variation in supply voltage and also it can be used to maintain the supply voltage constant no matter the variation in load.
How do you measure current without connecting the load?
Without load there is no current so it is impossible to measure it.
How do you measure current passed through the load?
by connecting ampere meter in series with load.
How you can check load connected of transformer?
Measure the current and voltage on the secondary side.
What reading would you get if a voltmeter is placed in series across a load in closed circuit?
In series and across the load are contradictory statements. Some voltmeters are really capable of voltage, current and resistance measurements. To measure current the meter either has to be a clamp on type or one that goes in series with the load. You measure voltage drop across the load as described above.
How is power caculated?
The power used up by any electrical load is . . .(voltage across the load) x (current through the load) or (voltage across the load)2/(resistance of the load) or (current through the load)2 x (resistance of the load). These are all completely equivalent, and you have your choice of which oneto use, depending on which numbers you know or can measure.
Why watt-meter is required to measure real power delivered to a purely resistive load?
A wattmeter (not 'watt-meter') will always measure the true power of a load, regardles of whether that load is purely resistive or not. This is because a wattmeter effectively measures the in-phase component of the load current.
How is electrical power caculated?

Where does the volmeter and ammeter go in a circuit?
after incomer & before outgoing feeder, we connect ameter to measure amps.AnswerThe voltmeter is connected in parallel with the load and the ammeter is connected in series with the load, if you wish to measure the potential difference across, and the current through, that load.
How does load current varies with the load resistance?
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.
