Current is the rate at which electrons flow past a point in a complete electrical circuit.
Duty cycle is the ratio of time a load or circuit is ON compared to the time the load or circuit is OFF.
Capacitance is the ability of a component or circuit to collect and store energy in the form of an electrical charge.
A diode is a semiconductor device that essentially acts as a one-way switch for current.
AC frequency is the number of cycles per second in an alternating current (AC) sine wave.
Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
Resistance is a measure of the opposition to current flow in an electrical circuit.
Ohm’s Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
A digital multimeter (DMM) is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms).
These three measurements, all taken quickly at one outlet, provide you with a solid understanding of the building's electrical supply.
Basic information about what an oscilloscope is and how the test instruments are used in industrial settings for preventive maintenance and troubleshooting.
