Lab #3
1. What is Power in your own words?
2. Define what a Series circuit is.
3. How do you find Vt, It, and Rt for a Series circuit? Write out expressions.
4. Is the current always the same in a Series circuit?
5. Is the voltage always the same in a Series circuit?
6. Please build a Series circuit using VT = 5v, R1 = 220 ohms and R2 = 2,200 ohms. Please
find Vt, It, Rt, VR1, VR2, IR1, IR2, PT, PR1, and PR2. Please draw out the circuit diagram
as well. Please measure all values and confirm results. Please simplify the circuit if
possible and draw the circuit diagram.
7. Define what a Parallel circuit is.
8. How do you find Vt, It, and Rt for a Parallel circuit? Write out expressions.
9. Is the current always the same in a Parallel circuit?
10. Is the voltage always the same in a Parallel circuit?
11. Please build a Parallel circuit using VT = 5V, R1 = 100 ohms, R2 = 1,000 ohms, R3 = 330
ohms, and R4 = 220 ohms. Please find Vt, It, Rt, VR1, VR2, VR3, VR4, IR1, IR2, IR3, IR4, Pt,
PR1, PR2, PR3, and PR4. Please draw out the circuit diagram as well. Please measure all
values and confirm results. Please simplify the circuit if possible and draw the circuit
diagram.
