[edit] Common uses

A Common uses section would be useful. I'm trying to figure out if a voltage divider is a good way to step down a 12V power source to 5V, or if there's a better way... ~MDD4696 03:17, 7 July 2006 (UTC) Maybe an advantages/disadvantages section? Like power issues (current drain).

This would be a really bad way to do it, as the voltage is dependent on load resistance. You could do it with a voltage divider and a transistor, though.Flying fish 23:52, 24 March 2007 (UTC)

[edit] Question

Why is a jagged line used to represent resistors not the standard box shaped symbol?

They are both standard symbols. — Omegatron 21:38, 18 January 2007 (UTC)

Someone should modify the picture...it's far too large. Splat 10:21, 7 March 2007 (UTC)

[edit] Page moved back to Voltage Divider

I've moved "Voltage divider rule" back to "Voltage Divider", with the blessing of the original mover Karol Langner. The article is more about the device than the equation, and there are more pages that link to voltage divider anyway. Flying fish 15:09, 8 April 2007 (UTC)

[edit] Voltage divider with more than 2 resistors

It might be useful for this page to include an example where more than 2 resistors are used in the voltage divider to show how the voltage at various nodes is calculated. e.g. {(R1+R2)/(R1+R2+R3)}* Vin to provide the voltage at the first node after the first resistor in a circuit with 3 resistors and a device across the 2nd resistor (it would be the voltage at one of the device inputs). I realize it would be easier if I could provide a graphic of what I mean but I'm not able to do that right now so I hope my description is clear enough to explain what I mean. Thanks.

[edit] Amplifier

A voltage divider is not an amplifier so why is there a whole section on amplifiers? Biscuittin (talk) 20:54, 12 April 2008 (UTC)

The section on amplifiers was put in on 7 January 2008 and nobody seems to have queried it. Does anybody object if I delete it? Biscuittin (talk) 21:25, 12 April 2008 (UTC)
Do you mean this section? It was put there to demonstrate a practical application of voltage dividers. There's also a similar section in the current divider article. Don't delete them, but you could combine them both into a new article (probably the best thing to do). Otherwise just add a cleanup tag or something. -Roger (talk) 22:03, 12 April 2008 (UTC)

OK, I have added some explanatory text. I agree that the section should be moved to a separate article but I don't know enough about the subject to write it. Biscuittin (talk) 18:57, 16 April 2008 (UTC)
