Like.
edited as suggested. Thanks for the help -
SSteve4Physics replied to the thread Current through an inductor as a function of time.I get the same answer (ignoring the formatting issue noted below). The expression "##V/5R##" is wrong because it actually means ##\frac...

SSteve4Physics replied to the thread Current through an inductor as a function of time.Hi @palaphys. First, note that you have used the same symbol, ##R_{eq}## to mean two different resistances. That’s a recipe for...

SSteve4Physics reacted to shishykish's post in the thread Calculate the radius of gyration for a plane figure with Like.
Ha! Yes it is. I really could learn how to copy and paste properly!

SSteve4Physics replied to the thread The sign of the change in potential.I would call the potentials ##V_A## and ##V_B## because a and b are not points (they are limit-values in an integral). Consistent use of...
