Read each question carefully and show all your work. Use the formulas for Ohm's Law, series circuits, and parallel circuits to solve the problems.
1. Which of the following correctly states Ohm's Law?
V = I/R
I = V/R
R = V * I
V = I + R
2. A circuit has a voltage of 12 V and a current of 2 A. What is the resistance?
6 Ohms
24 Ohms
0.17 Ohms
10 Ohms
3. In a series circuit, the total resistance is the of individual resistances.
4. If three resistors (2Ω, 3Ω, 5Ω) are connected in series, the total resistance is Ohms.
5. Explain how to calculate the total resistance of two resistors connected in parallel.
6. Analyze the circuit diagram below and answer the following questions:
a) Is this a series or parallel circuit?
b) If each resistor has a resistance of 10Ω and the voltage source is 12V, what is the total current flowing through the circuit?
7. Adding more resistors in series decreases the total resistance of the circuit.
True
False
