| Circuit number | Capacitance (uF) | Resistance (K) | Calculated Time (s) | Observed Time (s) |
| 1 | 100 | 1 | 0.5s | 0.5s |
| 2 | 100 | 0.1 | 0.05s | 0.05s |
| 3 | 100 | 0.47 | 0.235s | 0.235s |
| 4 | 300 | 1 | 1.65s | 1.65s |
R x Capacitance in F x 5= total time to charge capacitor.
Eg.100-6 x 13 = 0.1
0.1x5 = 0.5s

Having a smaller resistor will result in having a faster charging time, provided the Vs and Capacitance stays the same.
Having a larger Capacitance will increase the charge time, just like as you would a bath to a pool at the same flow of water.
How or why does the capacitor /resistor affect the charge time
ReplyDeleteThe smaller the resistor the more current will flow through into the capacitor this will fill the capcitor faster. The bigger the resistor the slower the current will flow into the capacitor resulting in a slower charging time.
