Discussion Overview

The discussion revolves around the relationship between Planck units and conventional units of energy, specifically how many Planck units correspond to one Watt-second at a frequency of 60 Hz. Participants explore the definitions and implications of Planck units in the context of energy and electricity.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant seeks to determine how many Plancks per second equal one Watt-second at 60 Hz.
  • Several participants inquire about the definition of a Planck, with one suggesting it relates to the charge of the electron in the context of electrostatic units.
  • Dimensional analysis is presented by participants, leading to calculations that suggest a large number of Plancks per Watt-second, specifically 2.5 x 10^31 Plancks.
  • Another participant questions the validity of the calculations and the relevance of the electron charge in the context of photon energy as described by E=hv.
  • One participant expresses a personal research interest in converting house current into electrostatic energy for plant photosynthesis, indicating a desire to use Planck units as a measurement standard.
  • There is a suggestion that the inquiry may also relate to how many Joules are equivalent to one Planck energy, with a reference to an external source for further details.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definitions and implications of Planck units, with multiple competing views on their relevance to the discussion of energy and electricity. The calculations and interpretations of Planck units remain contested.

Contextual Notes

Participants express confusion regarding terminology and the relevance of certain physical constants, indicating that assumptions about the relationship between Planck units and conventional units may not be universally understood. There are unresolved mathematical steps in the dimensional analysis presented.

I hope someone can help me find quantity of electricity.

how big is a Planck? In other words, how many Plancks per one second (unit time) equal one Watt-second (unit energy) at 60 hz (377 radian)?

dimensional analysis:

h = Planck's constant
n = number of "plancks"

units(h/s) = Ws

n("plancks"/s)= 1 W/60 Hz

n = 1.67e-2 Ws^2/h

n = 2.5*10^31

are you sure?
1 Ws (watt second) = 2.5*10^31n

You seem to be confused by some of the terminology. The electron charge is irrelevant in the formula E=hv, which relates the energy of a photon (E) to its frequency (v) via Planck's constant (h). Physicists just call E "the energy of a photon", not "a Planck" as far as I'm aware.

At a frequency of 60 Hz, a photon would have the energy
[tex]E=h \nu = 6.63 \cdot 10^{-34} \text{ J/Hz} \ \cdot 60 \ \rm{Hz} = 4.0 \cdot 10^{-32} \text{ J, or} \ 4.0 \cdot 10^{-32} \ \rm{W \cdot s}[/tex]
However, apart from serving as an academic exercise, I know of no practical value in thinking about photon energies when dealing with everyday 60 Hz phenomena.

OR ... maybe you really are asking about charge, and how many fundamental charge units are flowing in an electric circuit?

(EDIT added) OR ... do you want to know how many Joules are equivalent to one Planck energy? Answer: 1.956 × 109 J. For details, see:

My hobbyist research is to convert house current into electrostatic energy (ultrasonic force) to aid house plant in photosynthesis (dissociation of water) during winter. This was a peculiar interest to plant enthusiasts of early 20th century. I am implementing modern apparatus of my own design and theories presented Harvey F. Lodish in Molecular cell biology. I wish to employ natural Planck unit as measurement standard.

My confusion is with measurements of house electricity being expressed in electron, whereby lepton is conveyed differently by publications Electricity and Matter, Recent Researches Into Electricity by J.J. Thompson.
