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?

Short Answer

Expert verified

Answer

Toroidal solenoid has geometric configuration

Step by step solution

01

Definition of solenoid

The term solenoid may be defined as the cylindrical coil of wire acting as a magnet when flowing carrying electric current through it.

02

Determine the feature of the toroidal solenoid give it this simplicity

If assume that magnitude over the entire cross section area then

ϕB=B.AϕB=μ0NiA2πr

If the flux through each turn same then

L=NϕB2πrL=μ0N2A2πr

Hence, Toroidal solenoid has geometric configuration.

In an L-R-C series circuit, what criteria could be used to decide whether the system is over damped or underdamped? For example, could we compare the maximum energy stored during one cycle to the energy dissipated during one cycle? Explain.

Question: A high voltage dc power line falls on a car, so the entire metal body of the car is at a potential of with respect to the ground. What happens to the occupants (a) when they are sitting in the car and (b) when they step out of the car? Explain your reasoning.

A heart defibrillator is used to enable the heart to start beating if it has stopped. This is done by passing a large current of12Athrough the body at25Vfor a very short time, usually3.0msabout . (a) What power does the defibrillator deliver to the body, and (b) how much energy is transferred ?

In the circuit shown in Fig. E26.49, C = 5.90 mF, Ԑ = 28.0 V, and the emf has negligible resistance. Initially, the capacitor is uncharged and the switch S is in position 1. The switch is then moved to position 2 so that the capacitor begins to charge. (a) What will be the charge on the capacitor a long time after S is moved to position 2? (b) After S has been in position 2 for 3.00 ms, the charge on the capacitor is measured to be 110 mC What is the value of the resistance R? (c) How long after S is moved to position 2 will the charge on the capacitor be equal to 99.0% of the final value found in part (a)?
