Homework Answers
a)
ANSWER : Material , Geometry
EXPLANATION:
Inductance of a coil is given by: L = u*N^2*A/L
where u = permittivity of core <---- depends on the material
N1 = number of turns of the coil
A = area of the cross section <---- depends on the dimension of the coil
L = length of the coil <--- also depends on the dimension of the coil
b)
As from the explantion above, indutance does not depends on the current

B.1. Figure B.1 shows a magnetic circuit whose parameters are specified in the table below. For a coil of 800 turns carrying 1.5 amp, determine the flux densities in each material, the inductance of the coil, the energy storage of the circuit, and the force between the faces of the air gap. Leakage flux and fringing at the air gap will be neglected Material Length Area 15.24 cm 3.23 cm2 300 15.24 cm 3.23 cm2 500 50.8 cm6.45 cm2 1000...
Does the intensity of a laser affect the amount of current that flows through a photo...
Does the intensity of a laser affect the amount of current that flows through a photo tube? Does the intensity of a laser affect the voltage across a photo tube? I'm working on a lab that has a video where you can adjust the wavelength and see the subsequent change in current or voltage measured, but I'm unable to attach it. I'm just hoping to understand these questions better conceptually. My thoughts on the first one: Yes, the intensity of...
