Hi,

I could really use some help. I have hit a wall with my studies.

3. The voltage (vc) across a charging capacitor at timeTis given by:

V_{c}= V_{s}[ 1 - e^{ -T/(CR)}]

Where the supply voltageisVs= 10v, the capacitanceC= 10μFand resistance R = 20KΩ.Determine:

3.1. The time for the voltage to reach 5v

3.2. The voltage at 1ms after charging starts

3.3. The rate of voltage change at 1ms after charging starts

3.4. Show that the rate of voltage change when the capacitor is discharging from the supply voltage value will be the same as when charging from the same value at an any given time

Any help you could provide would be gratefully recieved!

Thanks

Daz
