The math is easier with 1 volt, but it can be any voltage........

In last equation and source voltage = 1, x is voltage you've measured.

When source voltage ^= 1 : x = (voltage measured/voltage source) ]]> feeds@yuku.com (emsvitil) http://leadacidbatterydesulfation.yuku.com/sreply/3927 Fri, 06 Mar 2009 03:19:54 GMT http://leadacidbatterydesulfation.yuku.com/reply/3926/t/Way-to-measure-coil-choke-.html#reply-3926 ]]> feeds@yuku.com (AndyCraig) http://leadacidbatterydesulfation.yuku.com/sreply/3926 Thu, 05 Mar 2009 18:47:11 GMT http://leadacidbatterydesulfation.yuku.com/reply/3898/t/Way-to-measure-coil-choke-.html#reply-3898

Use a simple transformer as the sinewave generator.

Hook it up home power. Your frequency will be whatever you have (50/60Hz) ]]> feeds@yuku.com (emsvitil) http://leadacidbatterydesulfation.yuku.com/sreply/3898 Mon, 09 Feb 2009 01:55:26 GMT http://leadacidbatterydesulfation.yuku.com/reply/3895/t/Way-to-measure-coil-choke-.html#reply-3895 feeds@yuku.com (Bruno) http://leadacidbatterydesulfation.yuku.com/sreply/3895 Fri, 06 Feb 2009 05:33:50 GMT http://leadacidbatterydesulfation.yuku.com/reply/3894/t/Way-to-measure-coil-choke-.html#reply-3894


Top level of that site seems to be here, if you want to look around some more.

Vin is connected to the circuit you're... ]]> feeds@yuku.com (AndyCraig) http://leadacidbatterydesulfation.yuku.com/sreply/3891 Sun, 25 Jan 2009 00:11:33 GMT http://leadacidbatterydesulfation.yuku.com/reply/3890/t/Way-to-measure-coil-choke-.html#reply-3890

Here's what worked for me and doesn't require a signal generator.
Build the circuit mentioned above. It's insanely easy. Only two pages of theory/how-to and you can run with it:

I came across these two sites that explains how to measure an unknown inductance, if one does not have LCR meter. Have not tried the process myself as I have just acquired a new DSO off 'eBay' last week and do not have frequency generator as yet.
