Considering that the power loss of a resistor is RI^2 and the information in the manual’s background section, derive an expression for the energy lost through Joule heating in a resistor when a capacitor completely discharges

Find the hall coefficient of a silicon material used in a Hall generator with a gap distance is 2.0 cm. When a current of 300 A flows, the hall voltage is recorded as 10 V and a magnetic flux density of 0.2 T is produced. Lütfen birini seçin: a. 0.0461 b. 0.0074 c. 0.0695 d. 3.3333 e. 0.0033

Okay for   Determine the mathematical expression for the voltage vC and the current iC for the discharge phase. I got Vc = 8e-t/0.2s V and iC = -4e-t/0.2mA But I need help with the last question Plot the waveforms of vC and iC for a period of time extending from 0to 2 s from when the switch was thrown into position 1.

Consider the large inductor in Figure 3 with given number of turns N, core permeability μ, core cross section area A, and core diameter are given. Note that the core length l is equal to π times the core diameter. Answer the questions and pick an answer from the given choices. The coil is made up of copper wire that has a cross section area of 1 cm2, and the length of each turn is nearly equal to 1 m. Find the resistance of the coil. (Assume an operating temperature of 20o C). 1) 180.2 mΩ 2) 17.2 mΩ 3) 1.2 Ω 4) 850.5 mΩ

A piece of silver wire has a resistance of 1 ohm. Determine the resistance of alead wire one-third the length and one-third the diameter if the resistivity of lead wire is 30 times that of silver. NOTE: Please explain where did you get the variables so I can understand them. Thank you
