23. Determination of the charging and discharging of a capacitor to determine the time constant
- 00:26 Why is it necessary to take care with the polarities of the components?
capacitor - 1000 micro farad
resistor - 20000 Ohm
6 leads
3.0 v battery
0 - 20 v d.c. voltmeter
| Hazard | Risk | Control measure |
|---|---|---|
