Hi Everyone,

I am getting a strange error with the transformer power supply. I am adding it to a rectifier circuit.

[ATTACH=full]198506[/ATTACH]

When I check AC voltage of transformer without connecting it to the bridge rectifier, the reading in the multimeter showed 14V

But when I check reading after connecting the transformer to the rectifier. I added the location where I am checking the reading in the above circuit diagram.

it is giving me a reading of only 4V. I don't know what is happening.

Is my transformer is bad? I am using a 12v step down transformer.

please help me.

thanks
