ELECTRICAL COMPONENT CHARACTERISTICS
ELECTRICAL THE COMPONENT HAS AN EFFECT ON A
COMPONENT
DIRECT CURRENT ("DC") CIRCUIT
RESISTOR
INDUCTOR
CAPACITOR
DIODE
A RESISTOR PROVIDES AN OPPOSITION TO
CURRENT FLOW, AND RESULTS IN SOURCE
VOLTAGE DROPS THROUGHOUT A CIRCUIT. THE
ABBREVIATION FOR "RESISTANCE IS (R)", AND
THE UNIT OF MEASUREMENT IS "OHM (Ω)"
A INDUCTOR PROVIDES AN OPPOSITION TO
CIRCUIT CURRENT BY SLOWING THE
INSTANTANEOUS BUILDUP AND TRIES TO
MAINTAIN IT CONSTANT. THE ABBREVIATION FOR
"INDUCTANCE IS (L)", AND THE UNIT OF
MEASUREMENT IS "HENRY (H)"
A CAPACITOR CHARGES TO CIRCUIT VOLTAGE
AND TRIES TO MAINTAIN IT CONSTANT AND THEN
BLOCKS CURRENT FLOW. THE ABBREVIATION
FOR "CAPACITANCE IS (C)", AND THE UNIT OF
MEASUREMENT IS "FARAD (F)"
THE COMPONENT HAS AN EFFECT ON A
ALTERNATING CURRENT ("AC") CIRCUIT
REMARKS ABOUT THE
COMPONENT IN AC
A RESISTOR HAS A REACTANCE (X) TO
ALTERNATING CURRENT FLOW CALLED
"RESISTANCE (R)" AND THE UNIT OF MEASUREMENT
IS "OHM (Ω)". THIS OPPOSITION TO ALTERNATING
CURRENT FLOW IS CALLED "IMPEDANCE (Z)".
A RESISTOR IN AN
"ALTERNATING CURRENT
(AC)" CIRCUIT OPPOSES
CURRENT FLOW
A INDUCTOR HAS A REACTANCE (X) TO
ALTERNATING CURRENT FLOW CALLED "INDUCTIVE
REACTANCE (XL)" AND THE UNIT OF MEASUREMENT
IS "OHM (Ω)". THIS OPPOSITION TO ALTERNATING
CURRENT FLOW IS CALLED "IMPEDANCE (Z)".
A INDUCTOR IN AN
"ALTERNATING CURRENT
(AC)" CIRCUIT OPPOSES
CURRENT FLOW
A CAPACITOR HAS A REACTANCE (X) TO
ALTERNATING CURRENT FLOW CALLED "CAPACITIVE
REACTANCE (Xc)" AND THE UNIT OF MEASUREMENT
IS "OHM (Ω)". THIS OPPOSITION TO ALTERNATING
CURRENT FLOW IS CALLED "IMPEDANCE (Z)".
A CAPACITOR IN AN
"ALTERNATING CURRENT
(AC)" CIRCUIT OPPOSES
CURRENT FLOW
A DIODE ONLY CONDUCTS IN ONE DIRECTION FROM
CATHODE TO ANODE, SO IT IS USED TO PROVIDE
RECTIFICATION OF AC TO DC VOLTAGE
NOTES:
1. IMPEDANCE (Z) IS AN "ALTERNATING CURRENT (AC)" CIRCUIT TERM USED TO DESCRIBE ANY INDIVIDUAL OR COMBINATION OF "CAPACTIVE
REACTANCE (XC)', "INDUCTIVE REACTANCE (XL)" AND "RESISTANCE ('R')".
2. "CAPACITIVE REACTANCE (Xc)" AND "INDUCTIVE REACTANCE (XL)" ARE OPPOSITE IN POLARITY
