What is a class B push-pull amplifier?
What is a class B push-pull amplifier? Class B amplifier is the actual Push-Pull Amplifier. Efficiency of Class B amplifier is higher than Class A amplifier, as it consists of two transistors NPN and PNP. The Class B amplifier circuit is biased in such a way that each transistor will work on one half cycle of the input waveform. What is the meaning of push-pull amplifier? A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. This kind of amplifier can enhance both the load capacity and switching speed. What is the advantage of a class B push-pull amplifier? Explanation: A class B amplifier helps increase efficiency, and the figure of merit reduces. The q power dissipation reduces and cross over distortion increases. What is class B and class AB push-pull amplifiers?…

Is a rocket engine more powerful than a jet engine?
Is a rocket engine more powerful than a jet engine? The jet engine must be able to ‘breathe’ in order to function. Rocket fuel is considerably more efficient than jet fuel and rockets usually are more powerful. Is a rocket faster than a jet? Rockets definitely fly faster than jets. A supersonic airplane can fly faster than the speed of sound (1,236 kmh or 768 mph). The SR-71 Blackbird holds the record for fastest jet, flying at 3,418 kmh (2,124 mph). The Space Shuttle, though, accelerates to 29,000 kmh! How do jet engines differ from rocket engines? Unlike a piston engine (which uses a single stroke of the piston to extract energy), a typical jet engine passes its exhaust through multiple turbine “stages” to extract as much energy as possible. That makes it much more efficient (it gets more power from the same mass of fuel). Can jet engines be…
