Charging resistor

WebOct 15, 2013 · 1. The energy dissipated in a resistor charging a capacitor is equal to the stored energy in the capacitor, 1/2 * CV^2. When the cap is discharged, its stored energy is dissipated in the resistor. So the total energy in the resistor for one charge/discharge cycle is CV^2. Multiply this by the frequency and you get the average power in the resistor. WebMar 15, 2024 · The pull-up resistor (Rp) determines the DFP’s current provision capacity.
