also known as an SCR, is a rectifier in which the forward resistance can be controlled. Normally an SCR will not allow current to flow in either direction, but if you supply a signal to the gate of the SCR, it will allow some amount of current (based ...
but the measurement must be done accurately to avoid damaging your multimeter. Multiplying the voltage in a circuit, with the current flowing in the circuit, will give us the total power in the circuit, represented in watts. This is important in determining electricity usage. ...
By "clamping" the tester around the measured grounding electrode, it is similar to the method of measuring current with multimeter current clamp.The tester applies a known voltage through the transmit coil without the need for a direct electrical connection and measures the current through the recei...
Using a Multimeter to test the voltage on a LiPo Battery. Probe Types There are many differenttypes of probesavailable for multimeters. Here are a few of our favorites: Banana to Alligator Clips: These are great cables for connecting to large wires or pins on a breadboard. Good for performin...
A tip for testing SMT components with a multimeter Some SMD components are very small, and it is very inconvenient to use ordinary multimeter test pens to test and repair. First, it is easy to cause a short circuit, and second, it is inconvenient to contact the metal parts of the compone...
Use pullup resistors on all chip select signals. Verify tri-state behavior on MISO: use a tri-state buffer chip if necessary. Protect bus access with SPI.beginTransaction(settings) and SPI.endTransaction(). Step 1: Pullup Resistors for Chip Select & Reset Signals When multiple SPI devices ...

There are several methods to measure changing current waveforms using an oscilloscope. The simplest one is using a current shunt and measuring the voltage across it. Video power electronics current Test and Measurement Oscilloscope Shunt Resistors Multimeter Have any question realated to this Article?
In electronic circuits and some electrical appliances, components called resistors have precise values of resistance so that they can be used to control the value of current flowing in a circuit. Every electrical device or load has resistance. Resistance is like a restriction to the flow of ...
The ohm meter is one of the most basic pieces of electronic test equipment. It is often a range of settings on a multimeter (volt-ohm-milliammeter or VOM) as the ohm meter is a variation on the ampmeter, which measures small electrical current. There are
