Jan 24, 2012 · The "top line" Voltage is the I x R voltage drop in the line and the bottom line Voltage is the transmission voltage. So loss ratio is effectively resistive_voltage_drop / line_Voltage. So, for a given conductor of resistance R the percentage of power lost will increase as current increases and will decrease as voltage increases.

Oct 5, 2012 · The formula to calculate the output voltage is: So if we assume your input voltage ranges from 0-50V, we need to divide it by 10 to achieve 0-5V. If we also assume we want to load the input voltage with 100kΩ, then the calculations would something like: Vout / Vin = R2 / 100kΩ. 0.1 = R2 / 100kΩ -> R2 = 10kΩ. R1 = 100kΩ - R2 = 90kΩ

Aug 30, 2017 · The accepted creepage distance depends on the Comparative Tracking Index (CTI) of the pcb material (in the table it is the "material"), on pollution degree, if traces are on the same or different layers, if the required insulation is Basic, Functional, Double (or Reinforced), that depends on the working voltage of the connected circuits, also ...

Feb 4, 2015 · The issue seems to be how we are first taught about a direct relationship between voltage and current (that is, an increase in voltage renders an increase in current if resistance remains the same) and then we're taught about power lines that have high voltage and low current (because other wise we would need thick wires that carry high current ...

Oct 16, 2015 · When the voltage across an insulator gets too high, it is possible that the insulator will stop insulating and will instead start letting some current through. This current flow can cause damage. If voltages are high enough, dielectric breakdown can result in arcing, which can cause heating, pitting, etc.

May 22, 2016 · \$\begingroup\$ Interesting and simple way to measure high voltage, but as I see it you are unnecessarily complicating things. I suggest you forget the impedance of the meter. If you use for instance 100 kohms resistors all the way, the impedance of the meter has no importance at all. You are just dividing the voltage as you wish.

Nov 19, 2014 · A resistor is called for. If it's charged to 300V and you want to limit the current to 1-2A you need a 150-300 ohm resistor.

High voltage guarding. Assemblies operating at potentials in excess of 500 volts should be completely enclosed from the remainder of the assembly and equipped with non-bypassable interlocks. MIL-STD-1472G adds the following in Section 5.7.9.1.1: General background [...] All electrical systems of 30 volts or more are potential shock hazards.

Oct 20, 2020 · Do electrons go from high voltage to low voltage or from low voltage to high voltage? If by 'high voltage' you mean 'more positive voltage', then a mobile electron would tend to move to a high voltage electrode, as would all other negative charge carriers. Mobile positive charge carriers move to the less positive electrode.

Apr 13, 2017 · I was wondering if there is a way to measure the voltage waveform in consideration of the fact that the oscilloscopes I have available to me are rated for 300V rms. Measuring the current would be great also but not as much of an issue (I'm aware of this answer Measure current in high voltage (10kV) but I don't have the same materials).
