Let's say that you turn on the space heater and then look at the power meter outside. The meter's purpose is to measure the amount of electricity flowing into your house so that the power company can bill you for it. Let's assume -- we know it's unlikely -- that nothing else in...
Use your volt meter (see below) to measure the voltage. You want to make sure that the transformer is producing approximately the stated voltage (it may be high by as much as a factor of two -- that is okay). Your transformer is acting like a battery for you, so you also want to...
Total harmonic distortionis used to measure the distortion level of the original audio signal received by the speaker from the source device (phone, player, etc.). In the specs list, it can be marked as THD and it’s expressed as a percentage (%). Harmonic distortion is caused by the d...
The units of measure are means of quantifying a physical value (such as temperature, pressure, volume, mass, length and several others) and those working with refrigeration are constantly dealing with them. Therefore, it is important to know them, understanding what they indicate and...

To measure the amount of power the line transmits, you can multiply the voltage by the current. You can express these two ideas using an equation in which I represents current, V represents voltage and P equals power: P = V x I Let's consider the example of transmitting 1 megawatt. If...
Example 1: Using a 3-V VDD and 12-bit-resolution TSC, such as TSC2046, to control a 4-wire TS. A touch on the TS (1/3 on X-direction and ½ or center at Y-direction) can initialize the following actions: 1. Measure X-data: 2 How to Use TI's 4-Wire TSC to Control an...

In an electrical and electronic circuit, a voltage measurement is an essential parameter that needs to be measured. We can measure the voltage between a particular point and the ground or zero-volt line on a circuit. In a 3-phase circuit, if we measure the voltage between any of one phase...
See this for info on How to Measure and Adjust Bias.Adjustable Fixed Bias SystemPower Transformer on left supplies 50 volts AC to the Rectifier Diode. The AC power flows into the diode's negative terminal (cathode) so 50 volts of pulsing negative DC flows out. The 1K resistor and large ...
