- Check Your Understanding When using Kirchhoff’s laws, you need to decide which loops to use and the direction of current flow through each loop. In analyzing the circuit in Example 10.7, the direction of current flow was chosen to be clockwise, from point a to point b. How would the results change if the direction of the current was chosen to be counterclockwise, from point b to point a?PART (1) Assume capacitor is fully charged when switch is at position 'a' for about 10 minutes. The switch is changed to position 'b' at t= 0. What is the current in the circuit immediately after the switch is closed? Assume after some time, the current in the circuit is 80.0 mA when the switch is at position 'b'.
