What is uses of tapped coil?
If question is about a transformer's tapped coil then the taps are a way of getting different voltages from one transformer. The end of the transformer's coil is the common point and the taps to this common point will give different voltages depending on where in the coil the taps are taken from.
Why are both negative and positive voltages generated as the magnet passes through the coil?
In this context, 'negative' and 'positive' are used to indicate the sense, or direction, of the induced voltages, as voltages do not have electric polarity (+ or -). The direction of the voltage induced into a conductor is determined by the direction of that conductor relative to the magnetic field. As the coil rotates, the directions of each side of the coil reverse relative to the field, and the induced voltages reverse too.
What is Opto-Coupler IC'S?
to prevent the high voltages The main purpose of an opto-isolator is "to prevent high voltages or rapidly changing voltages on one side of the circuit from damaging components or distorting transmissions on the other side."[2] Commercially available opto-isolators withstand input-to-output voltages up to 10 kV[3] and voltage transients with speeds up to 10 kV/μs.[4]
Why AC is used in preference to DC?
It is much more efficient to transmit AC over long distances. Because using transformers you can convert to very high voltages, and then power transmission then involves much lower currents, so that losses in the transmission line I2R are much reduced. You cannot easily and efficiently convert DC to high voltages.
What is one factor that leaders in India should take into account as they evaluate different options for generating electrical power?
solar energy is renewable and affects the environment less than coal
Electric current from a generating plant is?
Electric current from a generating plant is a alternating current transmitted at high voltages, but usually used at low voltages.
When batteries come in different volts what does it mean?
It means they come in different voltages to supply power to different things that require different voltages.
What would be the 3 phase voltage on a frequency of 50 Hz?
Single phase and three phase voltages are not related to the frequency at which the voltage is generated. The frequency at which voltages are generated is governed by the speed of rotation of the generating device.
Need for generating high voltages in laboratory?
because in laboratory almost we are using only three phase equipents,so we require more pewer in laboratory, thats why we are generating high voltage in laboratory.
How many volts is in a battery?
Batteries come with different voltages.
How do different currents and voltages affect the body?
the body can act as a conductor
Can you change the plugs on English appliances to US?
you can but don't do it the voltages are different
What are the different voltages for DC?
Like AC, DC can be at any voltage.
Can you have batteries of different voltages?
Yes. The voltage is determined by the chemistry inside the battery.
How do you Calculate the contact rating of relay for AC and DC?
On the side of the relay there is a name plate that tells you the current carrying capacity of the contacts. It gives you the ratings at different AC voltages and a DC rating of the contacts at different voltages.
How far can electricity travel through air at different voltages?
20KV can throw a spark about a centimeter long in dry air. the distance at other voltages is directly proportional to the voltage. you should be able to calculate the distances for other voltages yourself from this info.
Is the national grid In UK the same as us?
No. The two run at completely different voltages.
