1. What is an electric field? Sketch the shape of the electric field around a single proton.
2. If a uniform electric field is pointing east, what is the direction of the force on an electron? What is the direction of force on a positive particle?
3. If electrons are flowing counter clock wise in a circuit, which way is the conventional current flowing?
4. Explain what current, voltage, and resistance are?
5. Describe the differences between circuits with resistors connected in series vs. parallel.
