Hi all i've been playing with electronics awhile and when reading about DC network analysis they always use two voltage sources in their circuit. I've realized that i don't really know how two voltage sources behave together does anyone have any links or books they'd recommend?

Thx for the reply I've read the battery part im more confused about network añalysis with more than one voltage. Source like this circuit I doñt really. Know how to calculate for voltages in circuit

Va=40i3
Vr1=10i1
Vr2=20i2
i3=i2+i1
10=Va+Vr1
20=Va+Vr2

Get the last two equations in terms of i1 and i2.
And solve the simultaneous equations.
I hope it works.
