The electrical characteristics of a device refer to its behavior and performance when subjected to electrical conditions. This includes parameters such as voltage, current, resistance, capacitance, inductance, and power consumption, which define how the device interacts with electrical signals. Understanding these characteristics is crucial for circuit design, ensuring compatibility with other components, and optimizing performance in various applications. Additionally, these characteristics can influence the efficiency and reliability of the device in practical use.
An electronic measuring device also known as a multimeter is used to check the electrical voltage in homes and industrial areas. The checks that need to be done before a multimeter is used is the to plug the black test lead into the black socket marked com. The red lead plugs into the red socket marked voltage and resistance.
The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
I've never heard of a meggameter. However, since the question is under the heading of Electrical Troubleshooting, I'm assuming that you are referring to a megohmmeter. A megohmmeter is a testing device that measures the resistance of insulators and insulation of electrical conductors. Since their resistance is generally very high, this device uses a voltage between 500 and 2000 volts at a fixed current. This combination can detect minute pinhole leaks in conductors that are not visible to the human eye. These pinhole leaks can cause arcing and eventually an electrical short.

Some of the checks that can be done to an electrical device before checking electrical resistance include the proximity of other magnetic fields and other electrical circuits. Measure electrical resistance while at a safe distance from strong electrical circuits.
Starting resistance in electrical circuits refers to the initial resistance encountered by a device when it is first turned on. This resistance can affect the flow of current and the performance of the device.
Before measuring electrical resistance with a device, ensure that the device is properly calibrated and functioning correctly. Check that the probes are clean and in good condition to ensure accurate readings. Additionally, ensure that the circuit is de-energized and that any capacitors are fully discharged to prevent damage to the measuring device. Finally, confirm that the selected measurement range is appropriate for the expected resistance value.

Before measuring electrical resistance with a multimeter or similar device, ensure that the device is set to the appropriate resistance measurement mode (usually denoted by the ohm symbol, Ω). Check that the probes are properly connected and in good condition, with no visible damage or corrosion. Additionally, ensure that the circuit being tested is de-energized to avoid damaging the measuring device and to ensure accurate readings. Finally, verify that the device is functioning correctly by testing a known resistor to confirm accurate operation.
We licensed electricians call the device an OHM meter.
A starter is an electrical device that requires the proper supply of electricity to operate properly. Weak battery or loose or corroded connections and it will not function properly.

A thermistor is a type of resistor that changes its resistance in response to temperature. In electronic devices, thermistors are used to measure and control temperature. They function by converting temperature changes into electrical resistance changes, allowing the device to accurately monitor and adjust temperature levels.
120V stands for 120 volts, which is the standard voltage used in most residential electrical systems in the United States. This voltage is supplied by the electrical utility to power household appliances, lighting, and electronics. When a device is plugged into a 120V outlet, the voltage provides the necessary electrical energy for the device to function properly.
That will depend on the temperature coefficient of resistance of the device, which could be positive (i.e. resistance increases with increasing temperature), negative (i.e. resistance decreases with increasing temperature), or zero (i.e. resistance is unaffected by temperature changes).
