Hi, i am executing an engineering project and i need to know the declination angle between true north and magnetic north in Lebanon. Can anyone tell me about a reference or an internet site which can help? Thank you. Mirna.

I think that the DC capacitor is polarized , so you have to pay attention when using it for the poles(+ and -) while it doesn't matter for the AC capacitor cz the voltage changes from + to -.
