How to calculate string efficiency?
1
Voltage across the string / (Number of discs * Voltage across the disc farthest from the conductor)
2
Voltage across the disc nearest to the conductor/Number of discs
3
Voltage across the string / (Number of discs * Voltage across the disc nearest to the conductor)
4
Number of discs / Voltage across the disc nearest to the conductor
