How many hours or minutes can a coil burn?
It depends on the size of the coil and the burn rate.
Why would one use root sum square for a calculation?
The square root of the sum of the squares (RSS) can be used to calculate the aggregate accuracy of a measurement when the accuracies of the all the measuring devices are known. The average accuracy is not merely the arithmetic average of the accuracies (or uncertainties), nor is it the sum of them. Let's say you are conducting a test to verify the resistance of a coil. The coil is built to have a resistance to within one percent of its nominal value. Further, say you have an ohm meter that is accurate to within 0.5 percent of the measured value, but the test leads introduce an uncertainty of two percent. What is the inherent accuracy of any measurement that you make with that set-up? Use RSS to figure it out. RSS = SQRT(0.0052 + 0.022) = 0.0206 = 2.06 percent. Note how the RSS result in this case is greater than the largest of the values under the radical. (BTW, that test rig isn't a very good one for verifying whether the coil is within spec. The rig's uncertainty is more than two times the tolerance of the coil.)
What is part of genarator?
The answer is the drive shaft,strong magnet,and the coil of wire
How are complex numbers used in electricity?
1. One way is to show the relationship between different components such as a resistor and a coil. That would be R+iXL. This shows that the coil impedence is 90 degrees out of phase with R resistance. 2. Another way we can use complex numbers is as an aid to visualize the complex fields around two conductors carrying current. Please refer to the RELATED LINK for a picture.
Which of the following statement about electromagnets is true?
Electromagnets are temporary magnets that are created when electric current flows through a wire coil. The strength of an electromagnet can be increased by increasing the number of turns in the wire coil, increasing the current flowing through the coil, or by using a ferromagnetic core material.
What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.
What would happen to the voltage and the magnet is withdrawn from the coil?
the voltage increases
What is most likely to happen if you where to place a magnet in a coil of current carrying wire?
It would spin.
What would happen to the voltage impulse value and the magnet is inserted in and withdrawn from the coil?
the voltage will be decreased
If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become more magnetic.
Why the the reading on the newton meter increases when a current passes through the coil?
because it becomes more magnetic therfore it the pull on the coil will increase
What would happen if the spark plug wire had high electrical resistance?
You would have a misfire and it may damage the coil if operated long enough in that condition.
What has to happen around a coil of wire to generate an induced current?
pass a magnetic field through the coil of wire.
What will happen if a 250 VDC coil is used to replace a 440 VDC coil?
The coil will burn out due to having almost double the voltage being applied to it.
What happen if coil and capacitor are connected in series?
series resonant circuit
What will happen in the absence of iron cylinder in a moving coil galvanometer?
it will not work
What will happen if you take a dc coil off its armature?
It will no longer be attached!
