How do you measure EMF?
Use a voltmeter.
What voltages does a computer's power supply convert 120 volts of alternating current from a wall outlet into?
A personal computer's power supply receives 120 volts of AC and converts it to 3.3, 5, 12 volts of DC power.Another answerThe secondary voltage could be any number of voltages depending on what the power supply was designed for. Your best bet is to get a DC voltmeter and measure the output voltage of each wire on the output side.
What does mc and mi refer to in voltmeter and ammeter?
moving coil & moving iron
How many type of component in NIC?
The components of NIC are : buffer pulse transformers lan dc/dc converters lan filters
What is the function of a filter capacitor in a power supply?
A: The function is to change the pulsating DC into a smooth DC by removing the peak changes. The results are very little AC variation riding on top of the DC value or simply referred as ripple.
What is a dc voltmeter?
It is a voltmeter which can only measure direct current.
What is an ac voltmeter?
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
Concept of ac voltmeter?
Red wire from a regular DC voltmeter should be connected to :
What are the applications for a voltmeter?
The primary application of a digital DC voltmeter is to display the amount of DC current present in a circuit. This is particularly handy when troubleshooting problems.
A dc voltmeter may be used directly to measure?
Polarity
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
1 Which of the foll instrument can be used for both ac and dc?
voltmeter
How many voltmeter and ammeter are in dc watt meter?
There is no volt meter or amp meter in a DC watt meter.
Which voltmeter will used for measuring 50kv dc?
Any standard voltmeter but however the voltage to be measured must be stepped down to a safe value using a Potential transformer.
A DC wattmeter essentially consist of?
power i.e current and voltage or ammeter and voltmeter
How does a DC generator used as a tachometer work?
Here we will just connect DC generator shaft with motor's rotating spindle. Now connect voltmeter across dc gen. and just calibrate voltmeter in terms of rpm. If you have worked with micro-controllers then it will be very easy using it's ADC input.
Is Voltmeter Scale showing Volts with wavy line DC?
A voltmeter scale showing a wavy line typically indicates an alternating current (AC) voltage rather than direct current (DC). In AC measurements, the wavy line represents the sinusoidal nature of the voltage over time. If the voltmeter is intended to measure DC voltage, it should display a steady value without any fluctuations. Always check the voltmeter's settings to ensure it is used correctly for the type of current being measured.
