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.
What else can I help you with?
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
Should a battery spark when connecting it to a device?
No, a battery should not spark when connecting it to a device. Sparks could indicate a short circuit or improper connection, which can be dangerous and potentially damage the device or the battery.
Should the battery spark when connecting it to a device?
No, the battery should not spark when connecting it to a device. Sparks could indicate a short circuit or improper connection, which can be dangerous and potentially damage the device or the battery.
When connecting a safety fuse in a circuit connect it to what?
When connecting a safety fuse in a circuit, it should be connected in series with the load it is protecting. This ensures that if the current exceeds the fuse's rating, the fuse will blow and interrupt the circuit, preventing potential damage or hazards. Always ensure the fuse is rated appropriately for the circuit to ensure proper protection.
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.
Is it normal for a car battery to spark when connecting it?
No, it is not normal for a car battery to spark when connecting it. Sparks can indicate a poor connection or a short circuit, which can be dangerous and should be addressed immediately.
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!).
Which wire should be connected first, the red or black wire, when setting up the electrical circuit?
When setting up an electrical circuit, it is recommended to connect the black wire first before connecting the red wire.
What effect if any does connecting an ammeter in series with a resistor in a circuit have on the current though the resistor?
Connecting an ammeter in series with a resistor in a circuit will not affect the current through the resistor. The ammeter measures the current passing through it, so it becomes part of the circuit and simply measures the current flowing through the resistor without changing it.
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
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.
