Explain the power rating of this bulb say 60W what if the voltage changes?
You can check it out yourself using these formulas. Watts = Amps x Volts. Voltage = Watts/Amps
What are 5 important events in Karl Benz life?
he traveled to new york the twin towers they found him hanging from his thong he had a atomic wegi
What is the product of binary 10.101 and 11.01?
Well ... 10.101 is binary representation for 2.625 and 11.01 is for 3.25. So the answer is 2.635*3.25.
For examples you can check this http://www.informatik.tu-cottbus.de/~cnoack/erm-cs/s2.pdf
Have a nice day!
Electrons in an active circuit either drift slowly, or just jiggle back and forth in one place.
DifferEnces of long vs short shunt DC COMPOUND MOTORS?
the basic difference is ,in short shunt motor the series field winding wont carry any current under no load condition whereas in long shunt motors series winding will carry no load current.....
What is the meaning of rated lightning impulse withstand voltage?
That is the voltage rating the product can stand up to. If the lightning withstand voltage was 100,000,000V, that means the item could get struck by lightning that is up to 100,000,000V without damaging it.
That is e.g. the resistance of a cold bulb before the bulb is lighted and heats up.
Will a generator work if the wire is not spinning but the magnet is?
Yes. One winding/magnet must spin. Some generators have two windings, one is stationary (the stator), and the other spins (the rotor). One of these windings is energized, making it an electromagnet (called the field winding). In most generators of this type, the field winding is the one that is spinning. This is due to the fact that the stationary winding is the actual output of the generator, thus experiences high currents - and it is easier to pass these high currents through stationary busbars to the grid as opposed to rotating equipment.
What is better for headphones one with 63 ohms or 24 ohms?
All things be equal, the 24 ohm will be better. The reason is because they'll be many times louder decibel wise. The 24 ohm headphones can make your eardrums bleed if connected to the right source. 16 ohm (if you can find em) on the other hand will blow your head clean off. If you plug the 63 ohm into most sources you'll probably find the volume level inadequate.
What area of science uses amps and ohms?
Amps, or amperes, are a measure of electrical current; ohms are a measure of electrical resistance. Both are widely used in physics.
Is there more resistance in the series circuit or the parallel circuit?
Ohm's Law says!
R=V/I
Resistance is directly proportional to Voltage. In series circuit, due to adding the resistance, total voltage will be increased, due to increasing of total voltage, total resistance of the series also be increased.
Why one phase shows 0 Amps while a delta connected 3 phase induction motor runs?
Cause 2 phase is applied to the motor and another phase is disconnected ... in this condition ur motor cannot run longer ,it will trip on over current or burn ur motor winding .
i know someones going to be on this sooooooooo....... they sag because the hydro workers know, from the heat the cbles will sag during the summer, so they start the sag so they cant sag anymore
What happens if you turn off the electric current in the solenoid?
If you turn off the electric current in the solenoid, the solenoid quits pulling its armature.
How many units of electrical energy is consumed by a 3 kW stove which is switched on for 6 hours?
18kwh
What is the difference between a phase to ground connection and a grounded wye connection?
A 'grounded-wye' connection describes a wye-connected supply, whose star-point (or common point) is grounded. This is essential in order to ensure stable phase voltages. I'm not sure what you mean by a 'grounded-phase' connection; if you mean a 'grounded-line' connection, then this is a short-circuit to ground from a line conductor.
What happens when you connect 230V ac supply directly to a diode?
You get a violent explosion as the diode vaporizes.
What were one of Tomas Edison's inventions?
he invented my dick presser where you could make money by sucking it

If you crank the shaft of a dc motor manually will the motor become a dc generator?
It depends on both the wiring of the motor and what if any residual magnetic field remains in the field windings. If there is some residual field, you will get some volts, but not many. If the motor has permanent magnets, it is effectively a dynamo.
If a 1.5 V battery is connected to a 330 Ohms resistor Calculate the current in the circuit?
Ohm's laws says it will be 1.5 vdc divided by 330 ohms.
Can I wire a 3 phase delta wiring l1 l2 l3 wrong?
When it comes to electrical wiring all connections can be wired wrong. This is when an electrician is called to correct the mistake.
How do you install an earthing system for telecom?
make separate earth pits far from the electrical system earth pits and test to have low resistivity then connect the system or tower.
How can current lag or lead voltage in an AC circuit isn't current a function of voltage etc?
Current can lag or lead voltage in an AC circuit when the load is what we call reactive. The idea that current is purely a function of voltage only applies when working with DC, or when working with purely resistive loads, such as light bulbs and toasters. Not so, when dealing with motors and power supplies.
What happens is that an inductor resists a change in current. That means that, given a particular voltage and current at a particular instant of time, if you change the voltage, the current will not immediately follow - it will lag - because the inductor is a stored energy device.
Similarly, a capacitor resists a change in voltage, which means that if you change the current, the voltage will not immediately follow - it will lag - also because the capacitor is a stored energy device. Flip over current and voltage in the analysis of a capacitor, and you find that the current will lead the voltage, as opposed to the inductor's current lagging the voltage.
This causes the phenomenon of power factor, which is basically the cosine of the phase angle between voltage and current. Power factor is the ratio of apparent power to true power.
What is steel tape armored cable?
Armored cable that has a inbedded tape that is used for grounding purposes.
The steel tape is wrapped around the inner conductors which carry the load current. A heavy rubber coating is applied over the steel tape layer. The steel and heavy rubber helps protect the cable from physical damage, e.g. by someone digging in the ground where the cable is buried.
