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 connecting the power generation equipment into the primary series circuit you should?
functional checks
Which type of circuit the parallel circuit are use?
they are used for more power than a series circuit so you should use this one.
When resistance and continuity test are made on electronic circuit components the circuit being tested should be?
Open
To test for resistance in a circuit should be energized or de-energized?
To test for resistance in a circuit, the circuit should be de-energized.
Should current be measured with the power off the circuit?
It will not be possible to measure current unless the circuit is powered and operating.
What should you check before permanently connecting a meter to a circuit?
flash check
Before connecting the power generation equipment into the primary series circuit you should?
functional checks
Why supply circuit breaker should be 4poles?
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.
What precautions should be taken when connecting an electrolytic capacitor in circuit?
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!).
What effect if any does connecting an ammeter in series with a resistor in a circuit have on the current though the resistor?
That depends on the quality (price) of the meter. Ideally it should have no effect.
Will the voltmeter work when ammeter is connected wrongly in a circuit?
The volt meter should work. The meter is connected across the supply where as the amp meter is connected in series with any load that it is metering. On larger installations to measure the amperage, a current transformer is connected around the conductor to be monitored. If a CT is used then the polarity has to be observed when connecting to an amp meter.
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
Should ethics be observed in research?
They should be observed because if they are not observed then people will not like you very much, and certain organizations will go after you.
Why should you not connect a 6 V battery into a circuit that requires a D cell?
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.
Will connecting to a new computer erase the songs?
Connecting your iPod to a new computer and connecting to iTunes should not erase the songs.
What is the design procedure for clamping circuits?
Clamping circuits use diodes and capacitors. First, the first circuit must be set up, then a?æsine wave should be input into it. The input and output should be observed and adjusted as necessary; then, the process should be repeated for the other circuits.
Why should the connecting wires in a bulb be of low resistance?
This is to avoid energy losses in the connecting wires.
