calculate total capacitance - ANSWER-add capacitances
calculate total capacitive reactance - ANSWER-X_C = 1 /
(2 * pi * f * C)
X_c= capacitive reactance
in ohms
f= frequency in
hertz
c= capacitance in
farads
calculate total load on an AC circuit with capacitors - ANSWER-
X_C = 1 / (2 * pi
* f *
C)
calculate the time to charge and discharge a capacitor -
ANSWER-time=RC
R= resistance of
circuit
C= capacitance of capacitor
in farads
,thermal circuit breaker - ANSWER-Thermal circuit breakers use
a bimetallic strip that heats up and bends when a certain level
of current flows through it. When the strip bends far enough, it
trips a mechanism that opens the circuit and interrupts the flow
of current. To reset a thermal circuit breaker, you typically need
to flip the switch on the breaker to the "off" position, then back
to the "on" position.
magnetic circuit breaker - ANSWER-Magnetic circuit breakers
use an electromagnet to trip a mechanism that opens the circuit
when a certain level of current flows through it. The
electromagnet becomes stronger as the current increases, and
eventually trips the mechanism when the current reaches a
certain level. To reset a magnetic circuit breaker, you typically
need to push the reset button on the breaker.
Electromagnetism - ANSWER-Electromagnetism is the physical
phenomenon in which electrically charged particles interact
with each other through the force of electromagnetism. This
force arises from the interactions between electric fields and
magnetic fields, and can be observed whenever electrically
charged particles are in motion.
Define inductance. - ANSWER-An induced voltage which is
opposite in direction
to the applied voltage.
henry (H)
, effect of an inductor in an AC system - ANSWER-an inductor
acts as a resistor
to AC current. It opposes changes in current and causes the
current to lag
behind the voltage in the circuit. This property is known as
inductive reactance,
and is measured in
ohms.
effect on an inductor in a DC system - ANSWER-an inductor
acts as an open circuit to DC current. It does not allow DC
current to pass through it and effectively blocks the flow of
current in the circuit. This property is known as DC resistance,
and is measured in ohms.
total inductance equation - ANSWER-Total inductance (L) = L1
+ L2 + L3 + ...
Inductive Reactance Formula - ANSWER-XL = 2πfL where
XL is the inductive reactance in ohms, f is the frequency
of the AC current in hertz, and L is the inductance of the
inductor in henries.
total load on an AC circuit with inductors - ANSWER-known: XL
= 2πfL 1. Total inductive reactance (XL) = XL1 + XL2 + XL3 + ...
(for series connection) 1 / Total inductive reactance (XL) = 1 /
XL1 + 1 / XL2 + 1 / XL3 + ... (for parallel connection)
