Motional emf -easy question(re-edited)
Hi guys ,:
i'm learning about the motional emf , because i will have to take an exam soon, but I've found something really confusin for me well :
they say that when a conductor is moving in a direction perpendicular to the field with constant velocity...
Thanks for your reply but I still don't get it ,why does the battery still 'drive' current when it's supossed to be zero, ? the solution says that the capacitor charges through both resistances , so after the capacitor is charged up and the switch is closed , the current at the circuit should...
RC circuits -- questions about the solution
First of all , greetings from Peru and thank you to all the people who help another people here,taht's awesome , please help me with this guys... Here's the statement
The solution is
ok my question is about the...
actually the original figure doesn't show that the branch at point "a" bifurcates. it only appears in the solution , but i guess i finally get it , i think it's because black dots (nodes) mean that there is always a bifurcation . now everything makes sense , thanks !!!!!
Hi tahnks for your reply well i don't think they are in series because in the solution they don't use the rules of resistances in seires or parallel to solve the problem .check it out . but i need to know why . if someone knows please explain
just a questiion aren't the 1-ohm resistance(upper left) and the 3-ohm resistance in series? . The definition for resitance in series is "Two or more elements are in series if they are cascaded or connected sequentially " ,aren't they sharing the same wire? so why aren't...
thank you guys for your quick replies ,but aren't the 1-ohm resistance(upper left) and the 3-ohm resistance in series? . The definition for resitance in series is "Two or more elements are in series if they are cascaded or connected sequentially " ,aren't they sharing the same wire? so why...
two simple questions about equivalent resistance and kirchoff laws!! pleaseeeee! :D
Hi everybody . greetings from Peru.I know it's a dumb question but help please .please read below
For the network shown in the figure, show that the resistance Rab =...
