Does the neon power supply for those beer signs in bars output high voltage AC or DC?
High Voltage AC.
What is the clearance from high voltage lines to signs?
The clearance from high voltage lines to signs typically depends on local regulations and safety standards, which can vary by region. Generally, a minimum clearance of 10 to 15 feet is recommended to ensure safety and prevent electrical hazards. It's essential to consult local utility companies and adhere to relevant codes to determine specific requirements for your area. Always prioritize safety and compliance with regulations when placing signs near high voltage lines.
Can kirchoff's voltage law be used to determine voltage drop?
Yes. Kirchoff's Voltage Law states that the signed sum of the voltage drops going around a series circuit is zero. Thus, if you know all but one, you can figure it out. You simply add what you know up, and what is left is the last drop. Don't forget to be consistent in your use of signs. If, for instance, you show a voltage or current source as a voltage rise, then it must be considered to be a negative voltage drop. Or vice versa, as the case may be.
What constitutes a hazardous voltage and how to recognize victims of electric shock.?
A hazardous voltage is typically defined as any voltage above 50 volts AC or 120 volts DC, as these levels can cause severe injury or death through electric shock. Victims of electric shock may exhibit signs such as unconsciousness, difficulty breathing, burns at the entry and exit points of the electric current, or cardiac arrest. It's crucial to assess their responsiveness and check for vital signs while ensuring the power source is turned off before approaching. Immediate medical assistance should be sought for any suspected electric shock victim.
How do you know if start capacitor de-energized after start up?
You can determine if a start capacitor has de-energized after startup by checking for a voltage drop across the capacitor terminals using a multimeter. If the voltage is close to zero or significantly lower than the rated voltage after the motor has started, the capacitor has likely de-energized. Additionally, some systems have built-in indicators or relays that disconnect the capacitor once the motor reaches a certain speed. Lastly, a visual inspection for signs of overheating or damage can also indicate proper function.

Plus and minus.
Do two plus signs make a minus?
NO!!!! Here is a table for multiplication/division of 'double (+/-) signs.'. (+)(+) = (+) (+)(-) = (-) (-)(+) = (-) (-)(-) = (+) Sometimes in higher level maths, you can have triple signs. Here is the table. (+)(+)(+) = (+)(+) = (+) (+)(-)(-) = (-)(+) = (-) (-)(+)(+) = (-)(+) = (-) (-)(-)(-) = (+)(-) = (-) It is irrelevant on the position of the 'sign'. NB If no sign is given, then read it as positive (+).
