### Circuits 1

1. 1. 1. What are the three basic parts of electricity? 1. 2. 3. 2. ______________ is the movement of electrons through a conductor . 3. What is the force which moves electrons? 1. 4. The opposition to the flow of electrons is called ______________________ . 5. What is the difference between direct current vs alternating current? 1.
2. 2. Type circuit: Identify and define: Identify and define: Identify and define: What is constant in this type circuit: This type of circuit is often called a ___________ divider.
3. 3. Type circuit: R1 = 100Ω R2 = 200Ω R3 = 75Ω VT = 12V RT = _____ I1 = _____ I2 = _____ I3 = _____ IT = _____ Write all formulas used: V1 = _____ V2 = _____V3 = _____
