Terms in this set (14) What is lockout? the process of blocking the flow of energy from an energy source to a piece of equipment and keeping it blocked out What are lockout devices? Devices
An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials—semiconductors and conductors—conduct electric current more easily. The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than semiconductors or conductors. The mos
Electric circuits are made up of three circuit components. These are resistance, inductance, and capacitance. These are called passive circuit
A measure of a material''s ability to store electrical energy in an electric field, characterized by its ability to polarize in response to an applied electric field.
Power supplies are electrical devices that deliver electric power to one or several loads. They generate the output power by converting an input signal into an
Electrical noise is the result of more or less random electrical signals getting coupled into circuits where they are unwanted, i.e., where they disrupt information-carrying signals. Noise occurs on
An electrical circuit is made up of two elements: a power source and components that convert the electrical energy into other forms of energy. We build electrical circuits to do work, or to sense
Proof of electrical isolation: Proof of electrical isolation is required to verify that all sources of electrical energy have been removed from the equipment or circuit.

Classifying signals is a way to organize the signals around us. It focuses design, testing requirements, measurement tools, and expected
In a very short space, the electrical signal of the action potential is changed into the chemical signal of a neurotransmitter and then back to electrical changes in the target cell membrane.
Electric signals can be classified on the basis of its behaviour into following two groups: Deterministic signal is the type of signal that follows a fixed and regular pattern means it can be determined and accurately produced. This type of signal has well-defined wavelength, frequency and phase.
An inductor is another passive device that can store or deliver energy but cannot generate it. An ideal inductor is lossless, meaning that it can store energy indefinitely as no energy is lost as heat. Inductors present a low impedance path to DC current and a high impedance path to AC current.
Signals in electrical circuits are defined as the change of voltage or current with time. In other words, electrical signals are electromagnetic or electrical waves that carry information in an electric network or circuit.
Being passive, passive devices do not provide gain, amplification or directionality to a circuit but instead provide attenuation as they always have a gain less than one, unity. Therefore passive devices can not generate, oscillate or amplify an electrical signal.
Signals are processed through various devices like ICs (Integrated circuits), transistors, and diodes. Some of the basic characteristics of the signal are discussed below: Amplitude: Amplitude is one of the main characteristics of any signal. It is defined as the maximum displacement of wave (current or voltage) from the time axis.
At some specific frequencies this type of signal has high concentration of energy. These signals are commonly used in communication centers. Some of the common examples of periodic signals are square wave, triangular wave, sine wave, etc.
