Capacitor Investigation Demo Board
This is a highly useful demo board, it makes the student to understand the charging and discharging of the capacitors. Here the external + 12V DC supply is used for charging the capacitors through the current limiting resistors. The charging curve/time can be viewed on CRO. Once the capacitor is fully charged, it can be discharged with the help of toggle switch (turning towards discharge). Again the discharge curve/time can be viewed on CRO. This phenomenon can also be demonstrated using current meter, only the polarity of motor should be connected properly. Here three different combinations of C & R are provided for observing different wave forms.
