Why do we convert Frequency Domain to Laplace Domain?
Why making capacity of the circuit breaker is higher than breaking capacity?
What are potential transformers?
Latest Answer: Potential Transformer is designed for monitoring single-phase and three-phase power line voltages in power metering applications. The primary terminals can be connected either in line-to-line or in line-to-neutral configuration. Fused transformer models ...
Why FET is known as voltage control device?
Latest Answer: Since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain so it is known as voltage controlled device.For example: In a MOSFET, the current from drain to source depends upon the width of the depletion ...
Why BJT is called current control device?
Latest Answer: Because the input current of the transistor controls the output current, for example in CE configuration base current Ib controls the output current Ic. ...
Why vestisial side band is used in TV Signal Transmission?
Latest Answer: Actually Double Side band transmission is not wasting any data while traonsmission. But the problem with DSB is its bandwidth required is more. SSB requires less bandwidth. But there is no practical device exactly cut the sidebands and low frequency ...
What problem arise if we use regulators without/before filters?
Latest Answer: Filters are used for reducing ripples. A regulator output will be having many ripples. So filters are used in a circuit for conversion of pulsating AC to DC ...
The output of the rectifier pulsating in nature, it consists of a desired DC component of voltage and unwanted ripple components. These ripple components are removed by placing filter circuit at the output
Latest Answer: Filters are used to remove the unwanted or undesirable components of a output
waveform, so the basic work of filters is to smoothen the output.From electrical devices we
are not getting perfect sinusoidal output, it contains a DC component i.e.
ripples, ...
Where will Digital and Analog technology come into play in the CCTV technology in terms of data storage.
Latest Answer: In digital technology, there are only two states, logic 0 and logic 1. They are fixed points. In analog technology, any two points can be represented as two logic levels. ...
In connections of MCB, is it necessary that the incoming side supply should be connected at top side of MCB.Whether this has any effect in tripping of MCB in case of fault ? ( If connected reverse, it
