A very long, straight wire carrying current i(t) and a rectangular single-turn coil lie in the same plane, as illustrated in Figure.Thewire and the coil are surrounded by air.
a. Derive an expression for the flux linking the coil.
b. Derive an expression for the voltage vab(t) induced in the coil.
c. Determine the rms value of vab, given that i(t) is a 10-A rms 60-Hz sinusoid, l = 10 cm, r1 = 1 cm, and r2 = 10 cm.
Determine the supply voltage E. Find the load resistors RL2 and RL3. Determine the voltage divider resistor R1, R2, and R3.
Suppose you have a 2 kW electric heater rated for 220 volt operation, which you intend to operate at a reduced power dissipation of 1kW. Calculate the proper amount of voltage you would need to achieve this reduced power dissipation
An insurance company has made you the following retirement offer. If you pay them $100,000 now, you will receive payments of $8000 a year for 10 years. After this they will pay you $9000 a year in perpetuity (for ever).
A carousel, starting from rest, is brought to a full rotational speed of one revolution per 5.00 seconds. The angular acceleration during the process is 0.300 rad/s2. The radius of the carousel is 6.00 m.
1. Derive the sensitivity for a voltage and current source excited Wheatstone bridge. 2. Show the balance condition for a Wheatstone bridge is also true in the sinusoidal steady state if the resistances are replaced with complex impedances.
