Table B2b shows the line constants for three different transmission lines. One of these lines is dispersionless, but not lossless. Identify which line this is, and calculate the relative permittivity of the dielectric within it. (You may assume the dielectric is also non-magnetic).

Marvin uses a long copper wire with resistivity 1.681.68 x 10-8 Ω⋅m and diameter 1.00 x 10-3 m to create a solenoid that has a 3.00 cm radius. Part A) Calculate the total resistance if Marvin uses 11.9 meters of wire to create the solenoid.  Part B) Assume that Marvin has used the full length of the wire to produce the solenoid (that, is you may neglect any length of wire necessary to connect the solenoid to an battery). Calculate how many turns are in the solenoid. Part C) A 3.00 Volt potential difference is applied across the wires of the solenoid. Calculate the current that passes through the solenoid. Part D) If the coils in the solenoid are separated so that they are evenly spaced across a total length of 0.1 m, what is the magnitude of the magnetic field along the central axis inside of the solenoid?

Impedance plethysmography is a technique that can be used to detect thrombosis—the presence of clots in a blood vessel—by measuring the electrical resistance of a limb, such as the calf of the leg. In a typical clinical setting, a current of 200 mA is passed through the leg from the upper thigh to the foot. The voltage is measured at two points along the calf separated by 13 cm.a. If the voltage measured is 17 mV, what is the resistance of the calf between the electrodes?b. If the average calf diameter between the electrodes is 12 cm, what is the average resistivity of this part of the leg?

A ground fault interrupter (GFI) is an electrical safety device which uses electromagnetic induction to compare the hot and neutral currents. If the difference between the two exceeds the GFI interrupts the circuit, as this is the maximum amount of harmless current that could "leak" into the human body. 25 mA O 250 mA 500 mA 50 mA O 5 mA
