Give me the idea to connect led for indication - Electronic Circuits Projects Diagrams Free

i have made the 12V battery charger with full wave rectifier.(simply using diode).doing this ,i don't know whether the line is in the battery or not.That's why if i place the led to show the charging status,how should i connect the led before that transformer.

Just connect the positive lead of LED via 1k resistor in the rectified DC +ive output, and ground the other leg..

And a blast from the past...

Seriously? Such a trivial question for a final year electronic engineering student. You claim your programming skills are poor, how would you rate your electronic skills? Do you attend class?
