Suppose you have a steady current running through an inductor. If you attempt to reduce the current very quickly to zero by opening a switch, an arc (a spark) can sometimes appear at the switch contacts. Explain why in 100 words or less.
Homework Answers
The induced emf in an inductor is equal to -L(di/dt).
Here, L is the inductance and di/dt is the rate of change of current.
When you remove the current is very fast, the rate of change of current becomes negative infinite.
that means very high.
When the emf becomes very high, it thus creates a spark.

When the current through a large inductor is interrupted with a switch, an arc appears across the open terminals of the switch. Explain why this occurs. (This effect can also sometimes be seen as a spark when you remove an electrical plug from an outlet at home).

1.A current flowing through you of more than 5 ma is considered dangerous. Why do we see warnings about high voltage, rather than high current? What voltages are dangerous even if the skin is dry? (Dry skin has a resistance of 100 kohms while wet skin can be much less.) An electroencephalogram (EEG) is a recording of differences in voltage observed on the scalp by attaching electrical contacts. If voltage differences that are observed are about 0.5 mv, and the...

Suppose that you are running a business and you need some extra space for one year. Your bank offers you a loan of $100,000 at 0% Interest. You consider borrowing this amount, buying the building, using it for one year, and then selling the building to pay back the loan. Unfortunately, the economy in which you are operating is experiendng deflation at the rate of 10% per year. After one year, you...

Suppose you are given a circuit with a 24 volt peak sinusoidal supply, going through a 100 ohm resistor, and then a diode, charging a 12v battery. We are asked to calculate the fraction of the cycle during which the diode conducts ( and therefore charges the battery ). Part of this example denotes the conduction angle to be equal to 2(theta). When calculating the angle at which the input is greater than 12V we utilize arccos to find this....
