usually, you can think of electricity like a water hose
voltage is like (~~) pressure
current flow (amps) ~~ flow rate
and resistance is present also - it cuts down on the flow (current) downstream
if there are 2 paths, then the electricity will flow down both of them ("parallel") and the amt. of current in each path will be set by the resistance
current will flow thru each thing on the same path (series)
first exception to the analogy is that the "water" has to have a ground to get "back" - the entire chassis (body) of your car is the ground (gnd); it looks like a bunch of little crosshatches on a vertical line in the schematic
