An image of a red rose is displayed on a computer screen. This image is then printed onto a piece of paper by a printer. When the paper is held up next to the screen, the images are almost identical. What is the difference
between the processes used to create these two images?

It equals just about 6,300 km per hour each day an week

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
