Hi all
our professor told us to design a project for full wave rectifier with bridge circuit.
well, i used 220v -to- 16v center tapped transformer and connected only one half of the terminals(the middle and right wires) to the bridge circuit (4 diodes). then, i measured the voltage on the terminals of the transformer and after the bridge and everything was fine (about 15.6v AC after the transformer and the same voltage DC after the bridge) , but when i applied a smoothing capacitor (47000uf/50v) after the bridge to reduce the ripple voltage and measured the voltage after the capacitor, it became 23v dc with no AC!!!
How 15.6v dc suddenly become 23v dc after the capacitor! i just can't get it.
any ideas on what i might have missed or forgot to do??!!
