Planck's constant ¿

[dabiznuss]

Planck's constant is defined as a unit of action ( energy * time) is power in any way&nbsp;related to planck's constant b/c power is defined as&nbsp;energy&nbsp;being transmitted, or the amount of energy required or expended for a given unit of time. Here we are in comparison with power Of E.M. waves? <div class="Discussion_UserSignature"> </div>
