hp 48 tutorial - electric circuit

circuitA circuit is constructed according to the schematics on the right.


  • E is a battery of EMF 10V
  • C is a capacitor of capacitance 0.1uF
  • R is a 1k ohms reistor.

Assume that capacitor is fully charged. At time t = 0, the switch is turned to position S1 and is left there for 5 seconds before being turned to position S2.


Obtain the equation relating the relating the charge, q, flowing in the circuit with respect to time, t. Show the ensential parts of your workings.
