If you intend to connect the oscilloscope to a circuit that is connected to the supply voltage, you must use an isolation transformer. But the oscilloscope shouldn’t be floated by the isolation transformer. The device under test should be floated. …
To measure inductance with an oscilloscope, you can use three frequent methods. The first one is the resonant frequency method, the second one involves using a resistor of known value and the third one is by using voltage-current slope. Inductances…
A radial capacitor has leads that come out from the same ends. In contrast, the leads of an axial capacitor come out at two opposite ends. Radial and axial, both types of capacitors have their uses. However, it is important…
An inductor can be used to charge a capacitor instead of a resistor. You can charge the capacitor to a higher voltage than the source by connecting a diode in series with the inductor. The diode disengages the capacitor from…
There are several ways to test a fuse without a multimeter including the light bulb technique, using an ohmmeter, visual inspection, etc. Using a fuse tester would be more accurate than using other instruments. A fuse is an electrical safety…
With some easy steps, you can test a Triac using a digital multimeter or an ohmmeter. While using a multimeter, a digital multimeter is suggested for this test as these kinds of multimeters show more accurate readings than analog ones….
MOSFETs (Metal Oxide Semiconductor Field Effect Transistor) are of four different types or modes. They may be enhancement or depletion mode or maybe N channel or P channel. How does a MOSFET work? Here we provide a Java applet tutorial of N…
The transistor is a semiconductor device used for the switching and amplification of weak signals. This article explains how does a transistor acts as a switch and the working of a transistor as a switch. At present, transistors are applied…
