Homework Statement
Imagine a simple circuit loop with a battery and two bulbs connected in series.
I'm having trouble with the voltage of them, where are the + and - poles on the bulbs?
At first I simply told myself that the current flows (using the passive convention) from plus to minus, and the + poles of the two bulbs are such that the current flows from + to -.
In a problem I had there's a bulb in parallell with one of the bulbs as well.
I used mesh analysis (2 meshes) and got that both currents are zero, so obviously something is wrong. Did a whole other stuff as well but have been keep getting different results, it's kinda frustrating since this is very basic.
Anyway, am I wrong to think that the current flows through the battery from + to - (passive convention)? or does it go from the + pole, through the circuit (not through the battery) and then on to the - pole of the battery?
