Different types of fire extinguishers

1.7 Different types of fire extinguishers

Fire extinguishers are used to put out small fires. They are of different types with each made to deal with a specific class of fire. They are classified according to firefighting material in the equipment. The following are the most commonly used:

Water Extinguishers

Usually used to put out fires on burning solid materials.

Foam Extinguishers

Used to put out fires on burning oils and chemicals.

Carbon Dioxide Extinguishers

Used to fight fires on burning gases or vapours.

Dry Powder Extinguishers

Used to deal with fires on burning, flammable liquids and some solids, such as wood and paper.

Water and foam are conductors of electricity. Therefore, they should never be used to fight electrical fires unless the supply of electricity is disconnected; carbon dioxide and dry powder extinguishers are recommended Instead.

Other Extinguishers

Besides the above commercially made fires extinguishers, sand, soil and other covering materials may be used to fight fires

Block diagram of AM transmitter and receiver with explanation

Block diagram of AM transmitter and receiver with explanation AM Transmitter : Transmitters that transmit AM signals are known as AM transmitters. These transmitters are used in medium wave (MW) and short wave (SW) frequency bands for AM broadcast. The MW band has frequencies between 550 KHz and 1650 KHz, and the SW band has frequencies ranging from 3 MHz to 30 MHz. The two types of AM transmitters that are used based on their transmitting powers are: · High Level · Low Level High level transmitters use high level modulation, and low level transmitters use low level modulation. The choice between the two modulation schemes depends on the transmitting power of the AM transmitter. In broadcast transmitters, where the transmitting power may be of the order of kilowatts, high level modulation is employed. In low power transmitters, where only a few watts of transmitting power are required , low...

Using the TLP250 Isolated MOSFET Driver Explanation and Example Circuits

I’ve already shown how to drive an N-channel MOSFET (or even an IGBT) in both high-side and low-side configurations in a multitude of ways. I’ve also explained the principles of driving the MOSFETs in these configurations. The dedicated drivers I’ve shown so far are the TC427 and IR2110. Some people have requested me to write up on MOSFET drive using the very popular TLP250. And I’ll explain that here. The TLP250, like any driver, has an input stage, an output stage and a power supply connection. What’s special about the TLP250 is that the TLP250 is an optically isolated driver, meaning that the input and output are “optically isolated”. The isolation is optical – the input stage is an LED and the receiving output stage is light sensitive (think “photodetector”). Before delving any further, let’s look at the pin configuration and the truth table. Fig. 1 - TLP250 Pin Configuration Fig. 2 - TLP250 Truth Table Fig. 1 clearly shows the input LED side and the receiving photodetector as well...
