A few questions regarding capacitors and solar cells...

1. What does 100n mean with reference to a capacitor?
2. Will I get a readymade inductor if I specify it's value(say 100uH)
3. In the following figure 'Out' is showing only one terminal of the audio out. Where should I connect the other terminal of the headphones?
4. What does a 12x solar panel mean? Does it mean that it has 12 solar cells attached? or It must give an output of 12Volts?

Thanx

100n=100nF=0.1uF
Headphone other pin connect to positive supply, and must be a high impedance type (1...2kohm)
The coil can be handmade on small ferrite.

If its a preferred value, you can purchase a ready made inductor..

100microhenries is a preferred value, getting one shouldnt pose any problem......

If i want to make an 100uH inductor, how do i go about it?

Which wire do i use? How many turns should i have? How do i know what i have made is an 100uH coil?

Hi thebigbasicq,

Here is a capacitor equivalents calculator.
You can download it for free at Moyer Electronics.

I'm not impressed with it,
using 1.5 megabytes to move a decimal point
is not my idea of good programming.
I dont like the layout much either.

But there you go, it should do just what you want.

Regards, John

About the first quote, it is in relation to the Solar Ni-Cd

charger. My questions are:
1. Can I use a bead type 100uH inductor?
2. The circuit of the Solar Ni-Cd charger requires a 12x solar batteries. What does that mean?

I am attaching the circuit.

Thanx
