The discussion revolves around calculating the electric current in a 20 ohm resistor, particularly in the context of a circuit involving parallel resistors. Participants are exploring the relationships between voltage, current, and resistance.
The discussion is active, with participants providing various insights and suggestions. Some guidance has been offered regarding the current divider concept, and there is an ongoing exploration of how to approach the problem, though no consensus has been reached.
Participants are navigating the complexities of circuit analysis, particularly in relation to parallel resistors, and there is an emphasis on the importance of understanding foundational concepts before proceeding with calculations.
You know the current through the parallel pair of resistors. How do you get from there to the current through the 20ohm resistor. You don't need voltage.nowayn said:Homework Statement
calculate the electric current in the 20 ohm resistor
The Attempt at a Solution
I have no idea where to start, but i thought maybe you should calculate the voltage first and then the voltage over the 20 ohm resistor.
wait so is the current there also 0,3A?phinds said:
Do you understand the concepts of series elements and parallel elements? If you are not clear on that then you need to GET clear on it before trying ANY problems of this sort, else you will be perpetually confused.nowayn said:
