Part 1: Answer the following questions (20 points)
● Name and describe the components needed to make a complete circuit.
1 Battery.
1 Connecting wire.
1 Resistor (say a BULB or so....)
1 Voltmeter (connected in parallel)
1 Ammeter (Connected in Series..)

● Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different.
● series and parallel alike: all resistances affect the net resistance, all components see current flow. series and parallel different: series components have identical current flows in all components, the current flow in the circuit. Parallel resistors may or may not have identical current flows in special circumstances (less than total circuit flow), but the net voltage drop across the parallel branches will be identical.

● Ohm's law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same.
● i n accordance with the law, if r became smaller, and V stayed the same, the current would increase. Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same.
● resistance allows for finite current flow with finite voltage applied. Resistance is what Nature shows in real circuits.

Question 1: Is the circuit you created a parallel, series or a series/parallel circuit? Support your answer with a description of this type of circuit. i created a parallel circuit, a parallel circuit has two or more paths for the electricity to flow, the loads are parallel to each other so has you can see my circuit has more than one path. Question 2: What is the purpose of the resistor in your circuit?…
