Explain Working of the Transistors as a Switch

by

The working of the Transistors as a switch is explained here. When a transistor is used as an electronic switch, the transistor is operated in the cutoff and saturation regions to open and close a circuit, respectively. The working of transistors as a switch plays an important role in digital electronics. Working of the Transistors …

3 Methods of testing a diode with multimeter and oscilloscope

by
Testing a diode

Testing a diode with a digital multimeter in two ways, diode testing portion, and ohmmeter. A diode test is considered passed if it shows low resistance/voltage drop on forward bias and high resistance/voltage drop in reverse bias. A diode curve tracer uses an oscilloscope for VI characteristics graph.

Difference between intrinsic and extrinsic semiconductors: P-Type and N-Type

by

A semiconductor is a type of electrical material, which is used in electronic devices like PN junction diode, transistor and many more a replacement for a vacuum tube. The semiconductor can be intrinsic or extrinsic, where extrinsic has N-type and P-type.
