Chapter 23: Q13PE (page 860)

Approximately how does the emf induced in the loop in Figure 23.57(b) depend on the distance of the center of the loop from the wire?

Short Answer

Expert verified

The coil must be inversely proportional to the distance.

Step by step solution

01

Define Electromagnetic Induction

When a closed coil is placed in a continuously changing magnetic field, an electromotive force is induced in that coil. This phenomenon is known as Electromagnetic induction.

02

Explanation

The magnetic field which is produced with the help of the wire is inversely proportional to the distance from the wire. So, it is said that the emf produced in the coil should be inversely proportional to the distance.

Therefore, the coil should be inversely proportional to distance.

What capacitance should be used to produce a\(2.00\,{\rm{M\Omega }}\)reactance at\(60.0\,{\rm{Hz}}\)?

Suppose you find that the belt drive connecting a powerful motor to an air conditioning unit is broken and the motor is running freely. Should you be worried that the motor is consuming a great deal of energy for no useful purpose? Explain why or why not.

The 5.00 A current through a 1.50 H inductor is dissipated by a \({\rm{2}}{\rm{.00 \Omega }}\) resistor in a circuit like that in Figure 23.44 with the switch in position 2 . (a) What is the initial energy in the inductor? (b) How long will it take the current to decline to 5.00% of its initial value? (c) Calculate the average power dissipated, and compare it with the initial power dissipated by the resistor.

In a recording of voltages due to brain activity (an EEG), a 10.0 mVsignal with an 0.500Hz frequency is applied to a capacitor, producing a current of 100mA. Resistance is negligible. (a) What is the capacitance? (b) What is unreasonable about this result? (c) Which assumption or premise is responsible?

The capacitor in Figure \(23.55\) (a) is designed to filter low-frequency signals, impeding their transmission between circuits. (a) What capacitance is needed to produce a \(100{\rm{ }}k\Omega \) reactance at a frequency of \(120{\rm{ }}Hz\)? (b) What would its reactance be at \(1.00{\rm{ }}mHz\)? (c) Discuss the implications of your answers to (a) and (b).
