Do I understand the physics problem correctly?
Do they simply mean a) has a total voltage of 3 V, b) of 4.5 V, c) of 1.5 V and d) of 1.5 V??
Calculating resistance/current/voltage?
I have a task here but I don't understand how to calculate the individual voltage drops and currents of the individual resistors Can someone please explain this?
Current-voltage characteristics?
Are b)-d) correct? Regarding e): In ohmic conductors, the electric current I increases proportionally to the voltage U. As far as I understand, light bulbs are ohmic conductors, but I don't understand what the question is trying to tell me.
Series and parallel connection?
For a) I'm still halfway to the answer, but for the rest I don't have a reasonable explanation. For b), I'd say it's because the current flows through all the resistors, and thus the resistances add up.
How do you arrive at this formula?
I'm writing a physics exam soon. I'm actually pretty good at physics, but I'm looking at a formula in my notebook and I don't understand how it's created. This is about parallel circuits. In parallel circuits, U1=U2. This gives us R1•I1=R2•I2. This gives us I: R2:I1 and R1/R2=I2/I1 (/ is the fraction bar). My question…
Calculate total resistance R?
Can anyone help me with this task? It's enough if you tell me the direction of current flow at each position. I can calculate the resistances myself, but the diagram confuses me.
Physics series/parallel circuit calculation method?
Hello, I need the calculation method for this problem. Does anyone know how to do this?
How to calculate the missing values of this circuit (step by step)?
Hello, Since I accidentally photographed the wrong task earlier, here is the question again! How do I calculate the missing values of the circuit? Can someone please send me the solution, but please explain it step by step.
Electrical engineering, series circuit, parallel circuit task. Sketch, current, resistance… calculate?
Hello, Unfortunately, I can't help my daughter with her homework. See photo. Could you please explain to us how we can solve this and the result would of course be great? thank you in advance
Physics homework series connection with capacitors?
Hello, I would be very grateful if someone could tell me if my calculations are correct, as we only started this topic last lesson and I'm not entirely sure… Tasks 2 and 3 (The figure below belongs to No. 3) My calculations Thanks in advance 😉
