wattmeter
The "produced energy" would most likely be transmitted in the form of an electrical current; you can use standard equipment to measure that. If you manage to measure the voltage, the current, and the power factor, you can multiply everything together to get the power; multiply power by time, and you get energy.
What instrument do we use to measure the electrical and mechanical vibrations
It is a measure of electrical power. It is Voltage multiplied by Amps. All electrical applicances should give it's wattage or at least it's voltage and Amps so you can work out the wattage. It should be noted that that figure is the maximum that appliance would use.
Moving electrical power from generating point to use point.
To measure the current in an electrical circuit.
we use generators to create electrical energy. without them, no one would have power.
The unit is ampere (A).
The load that is connected to the circuit is what draws the power of the electrical circuit.
This steam cleaner does not use any electrical power.
Electrical generators produce electric power, and generators solve the problem of production. We use electricity in countless ways, and we need to access some kind of generator if we can't directly access the power grid.
