Experiment #5 The Capacitor



T = R x C x 5

Calculated Times:

0.0001 x 1000 x 5 = 0.5s or 500ms
0.0001 x 100 x 5 = 0.05s or 50ms
0.0001 x 470 x 5 = 0.235s or 235ms
0.0003 x 1000 x 5 = 1.5s

27/10/10 Correction for 330uF: 0.000330 x 1000 x 5 = 1.650s or 1650ms

Observed Times: 1: 0.5s
2: 0.2s
3: 0.3s
4: 1.8s

How does changes in the resistor affect the charging time?: As resistance increases the time taken to reach maximum charge increases also.

How does changes in the capacitor affect the charging time?: Like increased resistance, the larger capacitor will take longer to charge and also because of the larger capacity will take longer to discharge
