    Thermal energy/ heat in a parallel connection

    Thanks for the help 👍 One more question though, if the two resistors were in series would it be W1 : W2 = 1:2

    Thermal energy/ heat in a parallel connection

    The current flowing through R1 is double the current flowing through R2

    Thermal energy/ heat in a parallel connection

    In a parallel connection heat is produced. R1 = 5 Ohm R2 = 10 Ohm What is the relation of W1/W2? 1:4 1:2 2:1 1:8 3:1 I’d tend to say 1:2, but I am not really sure…

    Flow rate of a pipe - calculation

    Thanks, and yeah the one is just a straight line in the U.S. - right? But the fact that I am using the metric system also kind of gives it away, so ;)

    Flow rate of a pipe - calculation

    What is the difference between flow and flow rate?

    Flow rate of a pipe - calculation

    So, I guess that is the equation I was looking for?

    Flow rate of a pipe - calculation

    So, average speed equals volumetric flow rate times area? Just a bit confused, coz it was stated, that I have to find the flow rate

    Flow rate of a pipe - calculation

    So, I actually do not know, if the formula given applies to this problem or not, so I wanted to check

    Calculation with this electric circuit (battery and resistors)

    So c is incorrect. But how do I know which one of these two currents applies to a problem?
  10. A

    Calculation with this electric circuit (battery and resistors)

    That is what I got: potential a is -4V potential b -3V and potential c +6V, as the flow of current goes from the positive pole to the negative pole - at least that is what I read about it, but I find it kinda confusing

    Calculation with this electric circuit (battery and resistors)

    The current, to calculate the voltage drop
  12. A

    Calculation with this electric circuit (battery and resistors)

    12+5... I am still not sure if a is 2V or 22V
