**Instructions:**

Answer the following questions using the links provided (you may find another link if these aren’t working). Write your answers on a piece of paper and turn it in by the end of class. Most answers need more than a sentence to answer well.

- Find the electrical symbols for a Resistor, Light Bulb, Battery, Switch, and Capacitor (There are multiple ways to draw them, we will be going over them in class.)

- What is a short circuit and why is it bad?

- What is the definition of a series circuit? Include a circuit diagram of a series circuit.
- If you have a circuit with 5 light bulbs connected in series, what happens to the other light bulbs when any one of them burns out?
- What is the equation for calculating equivalent resistance in a series circuit?
- In a series circuit, what equation relates the current through the battery, and the current through each resistor?
- In a series circuit, what equation relates the voltage of the battery, and the voltage in each resistor?

- What is the definition of a parallel circuit? Include a circuit diagram of a parallel circuit.
- If you have a circuit with 5 light bulbs connected in parallel, what happens to the other light bulbs when any one of them burns out?
- What is the equation for calculating equivalent resistance in a parallel circuit?
- In a parallel circuit, what equation relates the current through the battery, and the current through each resistor?
- In a parallel circuit, what equation relates the voltage of the battery, and the voltage in each resistor?

- Why don’t birds get electrocuted when they land on high voltage power lines?

- Why do some plugs have 2 prongs while others have 3 prongs?
