1. What is the SI unit of electric current?

Volt · Ohm · Ampere · Coulomb

2. Which law relates the current flowing through a conductor to the voltage across it?

Faraday's Law · Ohm's Law · Kirchhoff's Law · Ampere's Law

3. What is the resistance of a conductor directly proportional to?

Length · Temperature · Cross-sectional area · Voltage

4. In a series circuit, the total resistance is equal to:

R1 + R2 + R3 · 1/R1 + 1/R2 + 1/R3 · R1 * R2 * R3 · R1 - R2 - R3

5. What is the effect of increasing the temperature on the resistance of a conductor?

Decreases resistance · Increases resistance · No effect · Depends on the material
