What is the purpose of the fuse box and relay in the car?
Purpose of the fuse box and relay in the car. Fuses limit current and protect against fire. Relays allow small control signals to run heavier equipment using larger signals, eg….
Category: What is Basic
This section cover question about what is basic electronics, what is use of different parts of electronic, circuit design fault and fundamental theory of electronics. solution of some critical circuits and hits and tips of electrical theory.
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 increases increase…
Atomic Structure
The smallest building blocks of matter are Called atoms. All atoms consist of three Basic components: the proton, the neutron and the Electron See illustration. Different Number and arrangement of…
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…
Power
Power is the rate at which the work is done or the electricity generated or consumed. The unit of measurement is the watt, and the letter identifier is “P”. electrical…
What is the difference between BJT and FET?
Difference between bjt and fet Main Difference between BJT and FET is that BJT is Current Controlled device and FET is voltage control device. They are developed from different semiconductor…
What is a diode for a doorbell?
Doorbell diode The included diode with your video ringing ring is used to connect the device to a digital sound of the sound. Digital sound signals are usually a speaker…
Why is 194 db the loudest sound possible?
The lower audibility limit is defined as SPL of 0 dB, but the upper limit is not as clearly defined. While 1 atm (194 dB Peak or 191 dB SPL)…
What is the loudest sound on earth?
The most powerful sound in the world. The sound of the Krakatoa volcano eruption in 1883 was so intense that it had broken the ears of people 40 miles away,…
What is an open loop gain?
The gain in an open loop of an amplifier is the gain obtained when no global feedback is used in the circuit. The increase of the open loop in some…
What is the difference between NPN and PNP proximity sensors
PNP sensors are sometimes called “supply sensors,” because the power supply is positive at the output. NPN sensors are called “diving sensors” because they sink at the exit. NPN and…
What is the difference between NPN and PNP transistors
Here i write in single line difference between NPN and PNP Transistor. full review will be added in later post. NPN transistor NPN transistor is the type of p-type bipolar…
What is the dark current of a photodiode?
When the photo transistor is placed in the dark and a voltage is applied from the collector to the transmitter, a certain amount of current flows. This current is called…
