We looked at circuits with resistors. Saw current, voltage, and resistance. The circuits included branches.
Current is the flow of electrons. Electrons have a negative charge.
Used Ohm’s law, V = IR and moved the variables around.
Current flows in an optimal combination when it comes to a branch. Electrons tend to flow where there is less resistance but the presence of more electrons creates more resistance.
Current flow is much like water flow through pipes. Though different in a few ways.
Used 1/R1 + 1/R2 = 1/R for two resistors in parallel.
