Question

Why are circuits important?

Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different.
Describe Ohm’s law and give an example of how Ohm’s law works.
Define resistance and describe why resistance is important in a circuit.

Answer 1

You should draw a diagram of each for this question.
In a series circuit, the resistors experience the same current. In a parallel circuit, they have the same voltage drop. Therefore, the equivalent resistance is calculated differently for a series and parallel circuit.
Ohm's law: V=IR
Resistance keeps a circuit from shorting.
