At moderate positive voltages, a diode essentially acts as a short, but with a small voltage drop. This is usually ... OR gate using diodes. For more practical scenarios, you can do some less ...

Perhaps you’ve also used them to generate a stable voltage drop ... simplified diode switch in the forward biased On position. This is a simplified circuit, but not by much. A practical diode ...

it’s often more practical and cost-effective to use one of the many integrated voltage regulators available today. Don’t jump to a Zener diode next time you need a low-current rail voltage ...
