Electrical Engineering

Thomas Edison was the inventor who wanted to develop affordable lighting for homes.

when someone eats you it is called that

not only for electrical people but also any engg. gaining of practial knowledge is easier than theoritical knowledge.but eee people has quite impotance than other[practical knowledge].in classes normally prof teaches but if they concentrate to into lab to show equipment.....engineers show they their tallent....becoz it is needed to work with that knowledge in their CORE COMP like ....APGENCO,APTRANSCO,APDISCOM,BHEL etc.,,,,,,,,,.........

Kirchoff's voltage law states that the signed sums of the voltage drops in a series circuit add up to zero.

Kirchoff's current law states that the current everywhere in a series circuit is the same, more specifically, that the signed sums of the currents entering a node is zero.

the most basic transformers have at least two coils, a primary and a secondary. A transformers nameplate will provide you with the max allowed voltage and current, as well as a voltage per turn ratio. for example a step down transformer could have a primary of 120 volts and a secondary of 24 volts this would give you a ratio of 5:1.

Yes, voltage effects the output of electric heaters. The wattage output rating of the heater will not be reached due to the lower applied voltage. For example if the heater is 5000 watts at 277 volts, the current is I = W/E 5000/277 = 18 amps. The resistance of the heater is R = W/I (squared) = 5000/18 x 18 (324) = 15.43 ohms. Applying 220 volts on the same heater whose resistance is 15.43 ohms results in this new heater wattage rating. W = E (squared)/R = 220 x 220 (48400)/15.43 = 3137 watts.

W = watts, I = amperage, R = resistance in ohms and E = voltage.

The dropper diode voltage regulator is a type of voltage regulator. It is comprised of a single diode that serves as the voltage regulating device.

Definitely EE at BITS Pilani. Firstly, EE is a better branch than Biotech in terms of placements and future job opportunities/growth. Secondly, BITS has always been ranked better than IIT-Roorkee.

This typically has to do with how many amps you can safely pull from the secondary of the transformer.

To determine polarity in CAPACITORS:

Electrolytic capacitors are often marked with a stripe. That stripe indicates the NEGATIVE lead.

If it's an axial leaded capacitor (leads come out of opposite ends of the capacitor), the stripe may be accompanied by an arrow that points to the negative lead.

Sometimes, you can look to the length of the leads as an indication of polarity. The positive lead is usually longer but be careful if you're reusing old or 2nd hand capacitors - the leads may have been trimmed.

Tantalum capacitors are often marked with a '+'sign.

what is the meaning of ac relay and dc relay

EDIT: a DC relay is simply a coil and core that pulls on an armature. An AC relay usually needs a shaded-pole core (couple of copper loops) to prevent the armature from vibrating at 60 cycles or so. The core, also, is laminated steel like a transformer; so is the armature to help contain the magnetic field. You should not substitute a DC rated relay for an AC , but the reverse should be ok, if voltage and current ratings are the same.

6.6 kV and 11 kV refer to the voltage rating of the fuse. 160A refers to the current rating. The 6.6 kV fuse is safe to use in a circuit with a voltage up to 6.6 kV and no greater. The 11 kV fuse is safe to use in a circuit with a voltage up to 11 kV.

Doing sex is an example of open loop

so in this system u cannot control the amount of sperms entering your partner

Yes it will operate it fine.

a current flow close to a magnetic source it influence the sources hall effect is a disturbed signal as a function of speed.

The difference between a Dy11 (delta winding lags the wye winding by 30 degrees) and a Dy1 (delta winding leads the wye winding by 30 degrees) is a phase shift. One is not better than another in a general sence. Depending on the configuration of the plant and surrounding power lines and transformers, one may be more beneficial than the other by allowing the plant to sync to the grid through multiple sources without first disconnecting.

i have never heard of a commentator in a motor, think you may be mistaking that word. inside an electric motor you have a stator and windings, as polarity changes it spins the stator and the brushes transfer the charge to the device being used..

I think they meant commutator. If you break an electric motor down to 2 parts, you have a commutator and an armature. the armature being the shaft that basically floats on bearings, and the commutator being the hull where the stator is. (and there is such thing as a brushless electric motor.) the stator does not spin. that is the term used for the magnets that pull the electric field supplied by the brushes. To make even more simple, imagine a shaft floating on bearings with 2 magnets on it, one positive and one negative ( the armature) and this shaft is inside of a ring of electricity the is flowing in one direction, its going to pull the negative and push the positive (the commutator) and cause the armature to spin.

Its Skilled Worker Program for Indian Student.

There are really bright chances to be settle in Canada for Qualified Indian Students.

20 colleges under SPP Canada all colleges are Govt. Approved colleges.

Tap changers are used to change transformer winding ratios by a specified amount (+/- 10%, for example). This allows more voltage control of one side with respect to the other. For a distribution transformer, as load increases, the voltage will sag. If it sags too far, a tap changer will be required to raise the voltage to acceptable values.

Feeder because the trolley will have overcurrent protection. Branch circuit is the final OCD to the load.

GFI Breakers are designed to an entire system of Receptacle's. they work by tripping any time there is an over load in the system , shorts and quick changes in current. make sure there isn't anything on other receptacle's. still occurs, put the load on it's own breaker..
