Item 9:

A capacitor is connected to a voltage source by resistive wires (resistance R a/b ).

For this circuit the voltage across the capacitor is starting from zero and is then increasing in time. This time dependence is influenced by R a/b and C.

Question:

Where can this time-depending voltage be measured?

 

Which of the following statements corresponds with what you know about this process.

  • 1) The time dependence of V, influenced by R a/b and C, can only be measured inside of the capacitor. The voltage between the wires a and b is determined by V 0
  • 2) The time dependence of V, influenced by R a/b and C, can only be measured just outside of the capacitor f.e. between 1a and 1b.
  • 3) The time dependence of V, influenced by R a/b and C, can be measured between 1a and 1b and around the points 2a and 2b but not between 3a and 3b.
  • 4) The time dependence of V, influenced by R a/b and C, can be measured all along the wires a and b ie between all the pairs of points 1ab,
    2ab and 3ab.
