Basic basic electronicsElectronics Terms For a signal, the angle of lead or lag between the current waveform and the voltage waveform.

A component whose value is determined by the amount of opposition it has to the flow of electric current.

An electronic circuit that produces a continuous output signal such as a sine wave or a square wave.

A formula used to calculate the relationship between voltage, current and resistance. It is expressed as VIR. Also expressed as E IR.

A unit of electric power dissipated as heat when amp of current flows through a component that has volt applied across it.

Zero volts. This is the arbitrary reference point in a circuit from which all voltage measurements are made.

The unit of measurement of capacitance. Named after English physicist Michael Faraday.

Electronic device or circuit that produces an output signal with greater power, voltage, or current that that provided by the input signal.

A particular of diode that will flow current at a definite reversebias voltage level.

A component that transforms an input AC voltage to either a higher level step up transformer or a lower level step down transformer AC voltage.

A component that conducts current in one direction only.

Number of cycles of a waveform that occur in a given time period, measured in hertz cycles per second. Hertz are named after the German physicist Heinrich Rudolf Hertz.

A set of formulas that for the basis for DC to AC circuit analysis.

A coil of wire whose magnetic field opposes changes in current flow when the voltage across the coil is changed.

The sum of all voltages in a loop equals zero

The unit of measurement of inductance. The Henry is named after American scientist Joseph Henry.

Electronic component if the form of a very small silicon chip in which numerous transistors and other components have been built to form a circuit.

The sum of all currents at a junction equals zero

The unit of measurement for the potential difference that causes a current to flow through a conductor.

The expenditure of energy over time. Power is measured in Watts.

A bipolar junction transistor BJT is a semiconductor component that can either be used as a switch of an amplifier. In either case, a small input signal controls the transistor, producing a much larger output signal.

The ratio of the number of turns in the primary or input winding of a transformer to the number of turns in the secondary or output winding.

A material that has electrical characteristics of a conductor or an insulator, depending on how it is treated. Silicon is the semiconductor material most commonly used in electronic components.

The property of a component that opposes any change in an existing current, measured in Henrys H.

The change in phase of a signal as it passes through a circuit, such as an amplifier or RC circuit.

The capability of a component to store an electric charge when voltage is applied across the component. Capacitance is measure in Farads

Total opposition resistance and reactance of a circuit to AC current flow, measured in ohms.

a component that stores electric charge when voltage is applied to it, that can return the charge to a circuit in the form of electric current when the voltage is removed.

An integrated circuit, multistage amplifier. An opamp is much smaller and, therefore, more practical than an equivalent amplifier made with discrete components.

The degree of opposition of a component to the flow of alternating current AC, measured in Ohms.

A connection from the output of an amplifier back to the input, where a portion of the output voltage is used to control, silize, or modify the operation of the amplifier. This is an integral concept to understand if you want to design or modify compressors or limiters.

The degree of opposition of a component to the flow of electric current, measured in ohms.

Inidual electronic parts such as resistors, diodes, capacitors, and transistors.

The process of changing alternating current AC to direct current DC.

A junction field effect transistor JFET, like the bipolar function transistor, can be used either as a switch or an amplifier. This transistor is found in the mous U FET Microphone.

Metal oxide silicon field effect transistor MOSFET; like the BJT and JFET, a MOSFET can be used either as a switch or an integrated amplifier. The MOSFET is the most commonly used transistor in integrated circuits.
