    Questions about current source and voltage

    hey guys, do ideal current sources have polarity? When I measure the voltage of a current source, it gave me a negative voltage. What does it mean? Also, can we use KVL in a loop containing a current source without converting it to equivalent voltage source?

    Would someone kindy give me some tips for Circuit analysis?

    I know that mesh method can only be used in loops without inside loops. Kirchhoff's laws for few unknowns. And nodal analysis can be used for analyzing almost all circuits, right? But what to use for an easier solution? I know that it is dependent to what is given but I just want to have an...

    Undergrad Creating a RL/RC/RLC Circuit model

    Hello! Would someone here guide me in creating a model for a RL/RC/RLC circuit? I have started studying this topic in advanced but I don't quite understand the concept in DE. I have watched videos from youtube.com and they solve problems using EE such as V=IR. And yes, I am able to answer...

    When was the thermometer brought indoors?

    Homework Statement at t=0; thermometer reading (x) =80 F (taken outside where the air temp is 20 F) at t=3; x=42 F then the thermometer is brought inside where the air is at 80 F. at t=10; x=71 F When was the thermometer brought indoors? Homework Equations temp=ambient temperature; x= present...
