A meter is any device that measures and may record an electrical or magnetic quantity, such as voltage or current. For example, an ammeter or voltmeter are kinds of meters. Use of such a device may be termed "metering" or you might say the quantity being measured is being "metered". As...

n n --.. 2(b) A student wants to investigate how the stopping potential is dependent on the frequency of the incident electromagnetic radiation.(i) Complete the circuit diagram in Fig. 8.1, showing the correct positions of the voltmeter, microammeter and variable e.m. f. source in order...
Source measure units combine the function of individual components into one unit. So, What is a Source Measure Unit? Overall, a source measure unit is a multi-talented tool for electronics, combining a power source and measurement functions in one. An SMU is a useful addition to any electrica...
The ampere metre, or Ammeter, is an electrical instrument that measures the electrical current in Amperes. By attaching an Ampere metre in series to the load, the electrical current on the load may be measured. Because it has no resistance, the measured circuit is unaffected. ...
What is a Digital Multimeter? Adigital multimeter, or DMM, measures and verifies multiple electrical quantities, including voltage, current and resistance. It’s a daily diagnostic tool used by technicians and electrical engineers and combines the features of a voltmeter, ammeter and ohmmeter. A ...
Electrical current can be calculated by measuring the voltage drop over a precision resistor with a known resistance, which is connected in series with the circuit. The current is calculated by using Ohm’s law. This is a called an ammeter orshunt resistor. Usually this is a high precision ...
4. When doing a DC withstand voltage or leakage current test, start by spinning the high-voltage silicon stack and micro-ammeter on the high-voltage output end of the high-voltage test transformer, then progressively increase the voltage to perform the DC test. Precautions for the use ...
Ammeter,instrument for measuring either direct or alternating electric current, in amperes. An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism; a shunt in parallel with the meter carries the maj...
This tool may also be known as a volt-ohm meter or volt-ohm-milliammeter (VOM). Techopedia Explains Multimeter New digital multimeters have advanced to the point that they can measure extremely tiny differences or fluctuations. Experts point out that although some multimeters test higher ranges of...
