This tool calculates the capacitor value for a full-wave bridge rectifier. The capacitor is used to smooth the output voltage to a specified ripple.

**Formula**

**C = I _{LOAD}/(f*V_{Ripple})**

where,

**I**is the load current_{LOAD}**f**is the frequency**V**is the peak-to-peak voltage ripple_{Ripple}

**Example Calculation**

For a load current of 1 Amp, 60 Hz frequency and Ripple Voltage of 1 Volt the required capacitor is 16.7 mF. To reduce the voltage ripple down to 0.5 V requires twice the capacitor or 33.3 mF.
