No, short to voltage and short to ground are not the same. A short to voltage occurs when a component is connected directly to a voltage source, bypassing the normal circuit path, which can lead to excessive current flow and potential damage. In contrast, a short to ground happens when a circuit connects directly to the ground reference point, potentially causing a fault condition that can also lead to damage. Both scenarios can be hazardous, but they affect circuits differently.
Voltage on ground can mean an open ground. It can also mean (high) current on ground, due to a ground fault such as reversed neutral and ground.
When using an oscilloscope to measure voltage that is not referenced to ground, it's important to ensure that the oscilloscope's input is properly isolated to avoid ground loops or short circuits. You can use differential probes or floating measurements that allow you to measure the voltage between two points without a ground reference. Make sure to set the oscilloscope to the appropriate coupling mode and scaling to accurately capture the waveform. Always be cautious about the oscilloscope's common mode voltage limits to prevent damage to the device.
'Active high input' refers to a signal or input condition that is considered "active" or "on" when the voltage level is high, typically close to the supply voltage. This means that when the input receives a high voltage, it triggers a response in the connected circuit or device. Conversely, 'active low input' signifies that the input is active when the voltage is low, usually close to ground level. In this case, a low voltage level triggers the response.
unregulated voltage minus series regulator transistor drop.
A: a ground on an IC is just a reference to the lowest point of voltage that can be applied.
You mean the conversion from voltage V to voltage level LV. Voltage level LV = 20 * log V 117 volts equals 41.36 dB. The reference voltage 1 volt means 0 dB.

Yes. Any object that is above a reference level has positive potential energy; anything below that reference level has negative potential energy. For example, if the chosen reference level is the ground level, anything below the ground level has negative potential energy. Please note that the choice of reference level is arbitrary. What matters is the DIFFERENCE in potential energy between two positions - and that doesn't change, whether you choose (for example) the ground level, or some other level, as a reference level.
Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.

A Neutral, Common, or Ground.
To convert voltage levels to DB you must first specify a reference, then take 20 x log(base 10) of the ratio of the voltage level in question to the reference. For example, if the reference is 1 volt and the signal of interest is 100 volts, then the level in dbV is: 20 x log10 ( 100 / 1 ) = 40 dbV
The neutral to ground voltage in electrical systems is important because it helps to ensure the safety of the system. When the neutral to ground voltage is at the correct level, it means that there is a proper connection between the neutral and ground wires, which helps to prevent electrical shocks and fires. Monitoring and maintaining the neutral to ground voltage is crucial for the overall safety and functionality of an electrical system.

Classically, its height above the ground (or your reference level).
== == Science Major: Altitude is height above mean sea level (MSL) or true altitude, which means in reference to what sea level is on the ground, or height above ground level (AGL), which is also called absolute altitude, which means height above the ground with no reference to the ground's height above sea level. In example, if the sea level in a certain place is 100 feet and you are 250 feet above the ground, your altitude above sea level would be 350 feet, and your altitude above ground level would be 250 feet.
