Using a fixed 20 V from the power source and three lightbulbs that have the same resistance, how would you design a circuit that would allow at least one bulb to use maximum power (have maximum brightness)? 27. Test your idea by constructing the circuit. Record your observations of the power usage along different parts of the circuit below. Analyze 1. What happens to the current provided by a power source as more resistors are connected in series? more resistors are connected in parallel?

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
