## Charging of capacitor in RC circuit

Charging of capacitor in RC circuit Ask QuestionAsked 2 days agoActive yesterdayViewed 486 times6 When a capacitor is charged in a first order RC circuit, it charges exponentially. I understand this behavior via equations. But […]

Possible causes of problem and troubleshooting suggestions 1. The I2C bus might be overloaded. The I2C bus has a maximum impedance limit, around 400pF. So if you put too many I2C devices […]
