RC and RL time constants

Steps to Follow:

1. TC = 10mh/1 K ohm 2. I = VA/R1 3. TC 4. IMAX 5. Complete voltage drops of R1 via Ohms law

Amount of induced voltage produced by inductor depends on:

1. Permeability 2. Core length 3. Core cross-sectional area 4. Number of turns

"TC" or "T", tau

Used to represent the term of time constants.

Medium (core)

Made of a variety of materials, commonly a ferromagnetic compound, iron, or air.

Inductor

Opposes change in current when added to a circuit. MAX current flow is no longer instantaneous. More inductive circuit = longer time constant. Less inductive circuit = shorter time constant. Consista of a length of wire coiled around a given medium (core). Either fixed or variable. Store a charge or oppose a current.

T =L/R

Rate of change is obtained by calculating the circuits' time Constants T: Time in seconds L: Inductance in Henrys R: Resistance in ohms

RL time constant

T = L/R Determines time required for current in inductors' to reach a specific value. Each successive time constant = current increasing by 63% from the existing value to MAX voltage potential. Max current is achieved by after each elapse of five time Constants.

Formula for charging or discharging a capacitor

TC = R * C

Kirchhoff's Laws and Ohm's Law

Teach us algebraic sums of voltage sources and voltage drops in a circuit and equal.

Inductance

The ability to store electrical energy by means of an electromagnetic field, is measured by the henry. Conductor creates an induced voltage when current flow is varied, AC or varying DC.

Resistance (R)

The opposition of current flow. Slows down the charging of the capacitor. Higher resistance? More time needed to charge the capacitor. Ohms

Capacitance (C)

the ability of a conductor to store energy in the form of electrically separated charges. Amount of charge a capacitor can accumulate. Higher capacitance? More time required to discharge a capacitor.

Actual time of one time constant

Depends on resistance and capacitance of the circuit.

RL circuit

A circuit that contains resistance and inductance. Represents current.

RC time constant

A fixed time interval set by R and C values that determines the time response of a series RC circuit. It equals the product of the resistance and the capacitance. Used to analyze the capacitor's cycles. Important in Non-sinsindual circuits to change shape and output of frequency. Indicate the rate of charge or discharge is a capacitor. Represent voltage. Charge and discharge. Inductor energizes and de-energizes. Take time of charge or discharge: RC time constants. Each time constant = length of time. It takes five time constants (five seconds) to fully charge or fully discharge a capacitor.

Capacitors

Go through a charge and discharge cycle.
