What is the resistor colour code?

What is the resistor colour code? Resistance values are often indicated by color codes, Resistor color code is identification of that resistor’s resistance, some resistor is very small in size…

How do you bias photodiode?

How do you bias photodiode? As the applied reverse bias increases, the photodiode current increases sharply. The blocking voltage applied at this point is called the breakdown voltage. This is…

Ohm’s Law

Ohm’s Law Ohm’s law states that the current is directly proportional to the voltage and vice versa proportional to the resistance. This means that as the voltage increases, the current…

What is Zener breakdown?

What is Zener breakdown? The Zener diode is a PN junction diode that was specially developed for operation in the blocking mode. In the forward bias mode, it acts as a…

What is an example of an enantiomer?

Just as our hands are mirror images of each other, molecules can also have mirror images that can not be superimposed on them. These molecules are called enantiomers. An example…

Resistance

Resistance Resistance is defined as the opposition against current flow. Some materials offer more Resistance as others. An example for is rubber. Rubber has more resistance in Compared to copper…

What is VDC power?

VDC is an abbreviation for “Volt DC”. DC stands for “direct current”, which means that the voltage is constant (in contrast to alternating current, alternating current, in which the voltage oscillates…

Types of Electricity

Types of Electricity Direct Current Current flowing in one direction only is called direct current. The letters “DC” Represent direct current. A battery generates direct current. The voltage source behind…

Why is earthing required?

Earthing provides a low impedance ground path for power if an insult fails and a live cable comes into contact with an exposed part of a device, causing the device…
