Calculation of resistance. A sphere made of a conducting material with conductivity 0" is connected in a circuit as shown in Figure 7.35a. For connection purposes, the sphere is trimmed and connections made to the flat surfaces created by the cuts. The resistance R and source voltage V are known.

(a) Calculate the potential on the sphere (between points A and B) in terms of the known parameters.

(b) Suppose that instead of cutting the sphere as in Figure 7.35a, the connections are made as in Figure 7.35b. Show that the resistance of the sphere cannot be calculated exactly and comment on the physical meaning of this result.

What will the slip ring voltage be in this case

If the slip-ring voltage is 400 V, when the rotor frequency is 120 Hz, at what speed must the rotor be driven in order to give 150 Hz at the slip-ring terminals? What will t

How much heat is transferred in the process

Heat is transferred to the vessel until one phase just disappears, and a single phase remains. Which phase (liquid or vapor) remains, and what are its temperature and pressu

Compute the real power in kw delivered to capacitive load

A 60-Hz, 440-V, three-phase system feeds two balanced wye-connected loads in parallel. One load has a per-phase impedance of 8 + j3 Ω and the other 4 - j1 Ω.

Calculate the magnetic flux in the core

Now suppose a 10-mm air gap is cut across the toroid. Determine the current that must be supplied to the coil to produce the same value of magnetic flux density as in part (

Find total real and reactive power delivered by the bus

A three-phase, 60-Hz substation bus supplies two wye-connected loads that are connected in parallel through a three-phase feeder that has a per phase impedance of 0.5 + j2 Ω

Calculate the final temperature of the mixture

Calculate the heat when 100.0 mL of 0.500 M HCl is mixed with 300.0 mL of 0.100 M Ba(OH)2. Assuming that the temperature of both solutions was initially 25.0C and that the

Develop a project plan and schedule of tasks
