There are 40 multiple-choice questions per session. Several disciplines require a common morning breadth exam which broadly covers the discipline and then a more detailed afternoon depth exam where the test taker selects a more detailed area of the discipline. Other disciplines essentially have morning and afternoon breadth exams. [4]
The questions on the Wiesen test, which are written at a sixth-grade reading level, do not require familiarity with objects encountered in specific events. Each question uses diagrams to illustrate mechanical principles. The questions found on the test are about the function, size, shape, appearance, and weight of common physical devices and tools.
An electrical component that stores energy in an electric field. capacitor-input filter A power supply network where a capacitor is the first element following the rectifier. capacitor voltage transformer In electrical power systems, an instrument transformer for measuring voltage that uses a capacitive voltage divider. capacity factor
High-precision laboratory measurements of electrical quantities are used in experiments to determine fundamental physical properties such as the charge of the electron or the speed of light, and in the definition of the units for electrical measurements, with precision in some cases on the order of a few parts per million. Less precise ...
Creates constant-amplitude variable frequency sine waves to test frequency response Transistor tester: Tests transistors Tube tester: Tests vacuum tubes (triode, tetrode etc.) Wattmeter: Measures power in a circuit Vectorscope: Displays the phase of the colors in color TV Video signal generator: Generates video signal for testing purposes Voltmeter
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism.
An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, [1] [2] such as electrical appliances and lights inside the home. The term may also refer to the power consumed by a circuit. This is opposed to a power supply source, such as a battery or generator, which provides power. [2]
A simple electric circuit made up of a voltage source and a resistor. Here, =, according to Ohm's law. An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances ...
