Chapter 4: Q3DQ (page 1012)

In Figure below, if coil2 is turned90° so that its axis is vertical,

does the mutual inductance increase or decrease? Explain.

Short Answer

Expert verified

Answer

The mutual inductance is decrease

Step by step solution

01

Definition of inductance

The term inductance may be defined as the property of electrical circuit to oppose a change in the electric current flowing through it.

02

Determine mutual inductance increase and decrease

The mutual inductance of coils is proportional to the coupling factor. When turn the coil decrease in coupling factor. There is no magnetic flux coupled if coilsperpendicular to each other.

Hence, the mutual inductance is decrease.

The power rating of a light bulb (such as a 100-W bulb) is the power it dissipates when connected across a 120-V potential difference. What is the resistance of (a) a 100-W bulb and (b) a 60-W bulb? (c) How much current does each bulb draw in normal use?

The tightly wound toroidal solenoid is one of the few configurations for which it is easy to calculate self-inductance. What features of the toroidal solenoid give it this simplicity?

The definition of resistivity (ρ=EJ) implies that an electrical field exist inside a conductor. Yet we saw that in chapter 21 there can be no electrostatic electric field inside a conductor. Is there can be contradiction here? Explain.

(See Discussion Question Q25.14.) An ideal ammeter A is placed in a circuit with a battery and a light bulb as shown in Fig. Q25.15a, and the ammeter reading is noted. The circuit is then reconnected as in Fig. Q25.15b, so that the positions of the ammeter and light bulb are reversed. (a) How does the ammeter reading in the situation shown in Fig. Q25.15a compare to the reading in the situation shown in Fig. Q25.15b? Explain your reasoning. (b) In which situation does the light bulb glow more brightly? Explain your reasoning.
