ENeuron = 14 million volts per meter! That’s more than four times the electrostatic force required to produce lightning during a thunderstorm!

### What is the resistance of human body from head to toe?

The internal body resistance is about 300 Ω, being related to the wet, relatively salty tissues beneath the skin. The skin resistance can be effectively bypassed if there is skin breakdown from high voltage, a cut, a deep abrasion, or immersion in water (Table 2).

### What is the voltage of Earth?

The line’s rated lightning impulse withstand voltage to earth is 650 kV peak phase to earth (nominal peak phase to earth voltage is 132 kV × 2 / 3 = 107.8 kV ).

## What is the voltage between live and earth?

230

The plug contains three wires – the live, neutral and earth wires. In a plug, the live wire (brown) and the neutral wire (blue) are the two wires that form the complete circuit with a household appliance….Live, neutral and earth mains wires.

Wires | Voltage between them (V) |
---|---|

Live and earth | 230 |

Neutral and earth | 0 |

### What is the range of voltage per conductor?

Watts/Line-to-line voltage X 0.667 = current per conductor. The range is 0.61 to 0.71 depending on head and volume of the water source and resultant operating frequency (PF). There are so many variables involved with wild frequency and the math is not simple, that this guide is intended to show distances that are most likely only.

### How to find the voltage of a wire?

Single-phase voltages are usually 115V or 120V, while three-phase voltages are typically 208V, 230V or 480V. Amperes – Enter the maximum current in amps that will flow through the circuit. For motors, it is recommended to multiply the nameplate FLA by 1.25 for wire sizing. Conductor – Choose the material used as a conductor in the wire.

### How much voltage drop does a feeder circuit need?

The National Electrical Code states that the voltage drop of a feeder circuit must not exceed 5%, and the voltage drop of a branch circuit must not exceed 3%.

## What’s the maximum voltage drop in a circuit?

This formula can help you determine voltage drop across a circuit, as well as the size wire gauge you will need for your circuit based on the maximum desired voltage drop. The National Electrical Code states that the voltage drop of a feeder circuit must not exceed 5%, and the voltage drop of a branch circuit must not exceed 3%.
