    Using Kirchoff's Voltage Rule to find currents in a system

    Thank you, that makes sense. How am i supposed to check the potential drop across the other resistors

    Using Kirchoff's Voltage Rule to find currents in a system

    Thanks, I am getting a bit confused with it all now. Just to check, am I correct in saying that across a component, if it is going from high to low potential, we can indicate this as a positive voltage. hence, for loop 1: considering the 'battery' the current would be flowing from low to high...

    Using Kirchoff's Voltage Rule to find currents in a system

    I used python to solve the matrix (using gauss elimination) and I am pretty sure I have done that bit correct (it was setting up the linear equations that I was unsure of)
