Terms Definitions
I= q/t
Biceps Triceps
Power unit Watta
electric conductance seamans (S)
reactance imaginary component of impedance
switch opens and closes a circuit
Esophageal intubation. Note the decreasing CO2 and the low baseline.
Lightbulb Bulb that lights up when heated.
Series What kind of circuit is this?
cuttoff the nonconducting state of a transistor
definition of current rate of flow of charge
When an electric current flows through an electromagnet, it becomes a ___ magnet
resistor A ________ regulates and slows down the flow of electrons by becoming more narrow or by conducting electricity poorly.
electrical symbols simple symbols used in circuit diagrams
Voltage drop The amount of potential difference across a resistor. -the amount of voltage required to push a specific amount of current across a resistor. -resistance increases so does the potential drop.
1/C = 1/C + 1/C + ... Series
A ____ is used to make electrical energy from chemical energy battery
Node Point of connection of two or more circuit elements
Schematic Diagram diagram that show elements of circuit using standard symbols
phase margin the difference between the total phase shift through an amplifier and 180 degrees; the additional amount of phase shift that can be allowed before instability occurs
Current-controlled voltage source V = rI(s) (r=constant) [+/- diamond]
digital signal   only a few restricted ranges of amplitude are allowed, and each amplitude in a given range has the same significance
in ___, total R is always less than the smallest R parallel
Series bEquivalent resistance The total number of resistance of circuit ; a single resistor that could replace all the other and have the same effect on the circuit
power gain the ratio of power delivered to the load to the input power of an amplifier
Electric Current the time rate of transfer of electric charge across a specific boundary. i = dq/dt (A)
closed circuit a circuit with the switch in the on position, so there are no breaks and charge can flow
differential mode the input condition of an op amp in which opposite polarity signals are applied to the two inputs
Kirchhoff's Voltage Law (KVL) The algebraic sum of the voltages around a closed loop must always be zero.
closed loop voltage gain the net voltage gain of an amplifier when negative feedback is included
A circuit must have no breaks in order for a current to ___. This is called a ___ ___. flow - closed circuit
where is bias supplied from for Q2 it is supplied through Rc1, the collector resistor for Q1
How do you measure current with an ammeter In an ammeter the current measurements are made in series, with 0 voltage drop across the meter. You must break the circuit where the current will normally go through
cos(wt+90deg)=
Ohm's Law R=V/I
bit  single binary digit
1 W equals 1 j/s
Circuit path containing easily moveable charges that electrons can flow through
Malignant hyperthermia. Note the rapidly increasing CO2.
conductor material through which electricity is easily transferred
Ammeter A device used to measure current
coax a transmission line, principally used for high frequencies, in which a center conductor is surrounded by a tubular conducting shield
in a _____, current DOES flow closed circuit
Home circuits are set up as parallel circuits
series circuit circuit in which electric current follows only one path
resistor-inductance circuits electric circuit comprised by resistor and inductor driven by a voltage source
One electrode on a battery is the positive ___ post. cathode
conductivity The resistance of a wire depends on the _________ of the material used in the wire
Circuits A closed loop that current can flow through Needed potential difference to put changes in motion in one direction
class A an amplifier that operates in the active region at all times
Alternating current (AC) Current in which electrons oscillate back and forth. -flow in a positive direction then a negative direction.
logic values   binary signals take on amplitudes in only two ranges, and the information associated with the ranges is represented by logic values 1 or 0
poles area of a magnet where the force is strongest
Series Elements are connected Current has End to end One loop
push-pull a type of class B amplifier with two transistors in which one transistor conducts for one half-cycle and the other conducts for the other half-cycle
root mean square square root of arithmetic mean of squares of the numbers in given set of numbers
Parallel path The # of paths = the # of resistors
input offsed current (Ios) the difference of the input bias currents
kirchhoff's current law (kcl) states that the algebraic sum of currents entering a node (or a closed boundary) is zero
do you need bias resistors no, since the stages are directly coupled, bias current for Q2 is supplied by Q1, eliminating the need for any bias resistors for Q2 and eliminating a coupling capacitor between the stages
Generators do not give off Circuit charges , they only charge in pen direction
common mode rejection ratio (CMRR) the ratio of open loop gain to common mode gain; a measure of an op amp's ability to reject common mode signals
