What is the relationship between the frequency of the voltage
source and the capacitive and inductive reactance? In other words,
if the source frequency increases or decreases, then what happens
to the capacitive and inductive reactance? Provide an example
A delta connected load has a parallel combination of resistance
5Ω and capacitive reactance –j5Ω in each phase. If a balanced three
phase 400V supply is applied between lines, find the phase currents
and line currents and draw the phasor diagram
Describe the principles and operations of proximity sensors:
Inductive, Capacitive, and Photoelectric. State the advantage and
disadvantage of each type of proximity sensors.
An inductor has a 43.6 Ω inductive reactance when connected
across a 60.0 Hz
power source. The inductor is removed from this first power source
and then
connected to a 52.0 Hz power source that produces a 80.0 Vrms
voltage.
a. (5 points) Draw a clear physics diagram of the problem.
b. (4 points) What is the inductance for this inductor?
c. (6 points) What is the maximum current in the inductor when
connected to the
52.0 Hz source?
d....
Give a detailed physical explanation (answer why and how) the
inductance (therefore reactance and impedance) of a large
synchronous generator is frequently assumed to have three distinct
values (sub-transient, transient, and synchronous).
Deductive, valid OR Inductive, reasonable OR Inductive,
unreasonable
1) If was an amateur theft. Matt's fingerprints were the only
ones on the safe. Amateur thieves nearly always leave fingerprints.
Therefore, Matt was the thief who broke into the safe.
2) Both presidential candidates have attended college. Most
people who have attended college have graduated from high school.
Therefore, both presidential candidates have graduated from high
school.
3)Cats never play frisbee. So your cat certainly doesn't play
frisbee.
