Ohm’s Law

Ohm’s Law

Ohm Law What is ohm’s law In the electrical field, Ohm’s law is a very important topic. This law is asked in almost all interviews and as basic fundamentals of electrical engineering for all who related to electrical engineering. This is a very important fundamental law that describes the Relation between Current, Voltage, and Resistance. There are three main quantities […]

Operational amplifier (Op-amp)

Operational amplifier (Op-amp)

Operational Amplifier (op-amp) An operational amplifier or op-amp is basically a multistage, very high gain amplifier having very high input impedance (typically a few Mega ohms) and low output impedance(Less than 100 ohms) and has the capability to amplifying signals of frequency ranging from zero HZ to 1MZ. Opamp is basically a multistage, direct-coupled, negative feedback amplifier that uses voltage […]

PIN diode Working, Structure and Application

PIN diode Working, Structure and Application

PIN diode What is PIN diode A PIN diode is one type of diode in which a wide undoped (pure form),  intrinsic semiconductor region placed between (sandwiched) a P-type and N-type semiconductor region. This intrinsic semiconductor layer has high resistivity. The high resistive layer of the intrinsic region provides the large electric field between the P and N-region. It differs […]

AC vs DC

AC vs DC

difference between ac and dc AC vs DC   AC DC 1 AC means alternating current DC means direct current 2 AC current reverses its direction periodically. AC alternates its direction within a circuit over time DC current flows in only one direction. DC does not change across time. 3 The magnitude of the current vary with time AC current […]

What is DIAC

What is DIAC

What is DIAC Diac is a device of the thyristor family. DIAC means Diode Alternating current. Diode + Alternating current. This is a type of diode that works in both reverse and forward bias. This diode work on the complete cycle of AC means this work during a positive half-cycle and also during a negative half cycle of the AC […]
