Because it has neutral with 3 phases. A supply circuit breaker is used on the lv side of the transformer to protect the equipment connecting to it.
Some people believe drunk drivers should lose their license permanently. Others believe they should be given another chance before this happens.
Most electrolytic caps are polarized, so they will only go in a DC circuit one way - if you reverse them, they will explode (wear goggles!).
That depends on the quality (price) of the meter. Ideally it should have no effect.
Connect ammeter in series and voltmeter in parallel to the circuit
polarity is of major importance in dicect current circuits. <<>> When using meters please remember that a volt meter does not connect into a circuit, the leads are placed across the component that you are measuring. It is an amp meter that connects into the circuit, becoming part of the circuit, to measure the current flowing through that circuit.
Before inspecting any electrical components or wiring you should disconnect the circuit from the power source.
A D cell battery supplies nominally 1.5V. Connecting a 6V supply in it's place would supply an extra 4.5V and could potentially damage the circuit components.
becouse if you have a good space you will get a promotion but if let it rot you will be fired
Connecting your iPod to a new computer and connecting to iTunes should not erase the songs.
This is to avoid energy losses in the connecting wires.
