State the principle of working of a transformer. (b) Define efficiency of a transformer. (c ) State any two factors that reduce the efficiency of a transformer. (d) Calculate the current drawn by the primary of
Explain the working of a piezoelectric device?Answer and Explanation: Piezoelectric devices work on the principle of tranferring energy between electric fields and mechanical forces using ferro-electric materials such as quartz.When the material is compressed or changes shape, its electrical field ...
Principle: The working of a rectifier is based on the principle that p-n junction diode conducts when forward biased and does not conduct when reverse biased. Arrangement: Circuit diagram of a full wave rectifier is shown in Figure. It consists of a step down transformer consisting of the ...
Briefly explain how an alternating current transformer works. And why are alternating current transformers so important to the world? what is the role of a commutator in a DC motor? How does a generator convert mechanical energy into electrical energy?
An electric toothbrush and its charger use a transformer just like a cellphone or an MP3 player, but it's cleverly split into two pieces, with half the transformer in the bottom of the toothbrush and the rest of it in the charger base it stands on:Artwork: Induction charging: half the ...
A Transformer model, trained to do nothing else than generate texts, turned out to be able to follow human language instructions that were contained in these texts, with no additional training ("fine-tuning" in AI parlance) required.With that out of the way, let's focus on the ...
Dmagnetic effect of the electricl current Submit Dlinear momentum Submit The principle of photo cell is View Solution Give the principle of separation in fractional distillation. View Solution View Solution View Solution View Solution View Solution ...
Explain why it would be better to improve the power factor as a method of improving the motor's output, rather than to increase the voltage input. Give the principle on which a transformer works. Mention the use of a ...
Briefly explain how an alternating current transformer works. And why are alternating current transformers so important to the world? Descibe 2 ways to create a magnetic field. Describe 2 ways to create an electric current. What are som...
Rectification. Rectification is the process of converting alternating voltage/current into direct voltage/current. A device used for this purpose is called rectifier and this phenomenon is called rectification. Principle. It is based on the principle t
