    Characterizing Voltage Sources: Finding V0 and r using a Variable Resistor

    Because V0 should be at lowest current (ie when it is 0) but the internal resistance keeps it from actually getting there?

    Ratio of resistance in parallel and series

    Homework Statement Two resistors R1 and R2, where R1 > R2, are connected to a voltage source with voltage V. When the resistors are connected in series, the current is Is. When the resistors are connected in parallel, the current from the source is Ip = 8.0Is. What is the ratio R2/R1? I have...

    Characterizing Voltage Sources: Finding V0 and r using a Variable Resistor

    Homework Statement A variable resistor, R, is connected to the terminals of a battery (dashed box in the diagram). The graph below shows data collected in the circuit as R is varied. What is V0, in volts? What is the internal resistance, r, in ohms? should the V0 be measured at the top...

    What is the current distribution in a circuit with complex resistors?

    Homework Statement Five resistors with resistance R1 = 4.90 Ω, R2 = 7.30 Ω, R3 = 8.80 Ω, R4 = 2.70 Ω, R5 = 5.00 Ω, are connected to a battery with emf E = 8 V in the circuit shown. What is the current in resistor R1? I also need the current through all other resistors. I know you need to use...
