    I am experimenting with a power supply using a 230 – 6v AC transformer feeding a bridge rectifier. The raw output of the transformer is 7.3v dc and the output of the bridge is 7.4v dc.
    However, on connecting a smoothing capacitor (470μ electrolytic) across the bridge output, the output voltage rises to 10.6 v dc. What is going on here?
    Should I add a resistor to drop the 10v to the required 6v?
