Most volt/amp meters have a DC mode. You measure DC voltage by putting the two probes across the voltage source. You measure current by either putting the meter in series with the load or using a clamp on amp meter that measures current flow through induction.
Yes, it will.
For DC circuits, an alebraic sum is required. For AC circuits, a phasor sum is required.
There is no volt meter or amp meter in a DC watt meter.
A DC motor converts electrical energy to mechanical energy. The converted energy is provided to a mechanical load.A DC generator converts mechanical energy to electrical energy. The converted energy is provided to the electrical load (voltage, current referring load).A DC motor can be used as a DC generator and vice-versa.
meter calibration by potentiometric method
The indicater meter is a DC device, so the rectifier changes AC to DC. A meter could not respond to AC.
Use a meter that simultaneously will test for both. Most better meters such as Fluke have this capability Or Switch your meter to AC if you get no voltage over the reading then likely you have a DC circuit. Don't do this by switching to DC first, You very well will ruin your meter if your meter does not have protection to handle this.
how much energy is lost in converting dc energy to ac energy
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
A DC clamp meter works by measuring the magnetic field produced by the flow of direct current in a conductor. When the clamp is placed around the conductor, it detects the magnetic field and converts it into a direct current measurement. This measurement is then displayed on the meter's screen.
You cant.
Yes but the meter has to go in series with the load. There is a new clamp on amp meter being introduced, that will measure larger DC amperages without opening the circuit.
