What else can I help you with?
When It is required to calculate average voltage and when RMS voltage?
It is usually required in electrical examinations to make calculations. Simple answer to a complicated calculation. Remember, take peak to peak voltage and multiply by .707, the result being average voltage. This is the voltage that electrical test meters read.
Why you use transformers to transfer power?
Transformers do not exactly transfer power, they either step up voltage or step down the voltage from one source to another to make it a useable voltage.
What component generates the high voltage necessary to make a spark in a vehicle?
The component that generates the high voltage necessary to make a spark in a vehicle is the ignition coil. It converts the low voltage from the battery into a much higher voltage, typically between 12,000 to 45,000 volts, which is needed to create a spark at the spark plug. This high voltage ignites the air-fuel mixture in the engine's combustion chamber, enabling the engine to run.
If voltage changes in a ac circuit what happens to current?
Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.
What is zener break down voltage?
The point in the forward operating region of the characteristic curve where conduction starts to increase rapidly is called Knee voltage of a PN Junction Diode.The breakdown voltage of a diode is the minimum reverse voltage to make the diode conduct in reverse.(or) Breakdown voltage is a parameter of a diode that defines the largest reverse voltage that can be applied without causing an exponential increase in the current in the diode.-- Dinakar
Can high voltage light dirrectly to your eyes make you feel dizzy?
It is true that high voltage light directly to eyes, can make someone feel dizzy.
When a circuit is inductive the current has what voltage?
This doesn't make sense, "current" is "amperage" so the higher the voltage the lower the amperage, and the lower the voltage the higher the amperage.
How do you charge a capacitor?
You charge a capacitor by placing DC voltage across its terminal leads. Make sure when using a polarized capacitor to place positive voltage across the positive lead (the longer lead) and negative voltage across the negative lead. Also make sure that the voltage you charge the capacitor to doesn't exceeds its voltage rating.
Is voltage used to make current flow?
Yes. Another term for voltage is EMF, electro-motive-force.
What is clockwork electricity?
it is voltage to make your clock run
How can make a voltage source inactive in superposition theorem?
To make a voltage source inactive in the superposition theorem, you replace it with a short circuit. This means that you eliminate the voltage across the terminals of the source, allowing current to flow as if the voltage source were not present. Once the analysis is completed for all other sources, you can then reintroduce the effects of the voltage source by considering its contribution to the circuit.
What is the recommended method for testing the voltage of a doorbell?
To test the voltage of a doorbell, use a multimeter set to the voltage setting. Disconnect the doorbell wires and touch the multimeter probes to the wires to measure the voltage. Make sure the voltage matches the recommended range for the doorbell.
When measuring resistance should there be a voltage applied to the resistor?
No, the meter used to make the measurement will be applying whatever voltage to the resistor it needs to make the measurement. Any additional voltage will disturb this, resulting in at least an incorrect reading and at worst damaging or destroying the meter.
When It is required to calculate average voltage and when RMS voltage?
It is usually required in electrical examinations to make calculations. Simple answer to a complicated calculation. Remember, take peak to peak voltage and multiply by .707, the result being average voltage. This is the voltage that electrical test meters read.
What range should you set the voltmeter prior to taking a voltage measurement?
Make a guess of what the voltage will be and set the range accordingly. If needed, change the range after measuring the voltage, to get a better reading.
Why you use transformers to transfer power?
Transformers do not exactly transfer power, they either step up voltage or step down the voltage from one source to another to make it a useable voltage.
What can make a 1998 Buick lasabre have high voltage?
