Read each question carefully and show all your work. Use the provided formulas and diagrams to help you solve the problems.
Ohm's Law states the relationship between voltage (V), current (I), and resistance (R): V = I × R
Power (P) can be calculated using the formula: P = V × I
1. The unit for voltage is the .
2. Current is measured in .
3. Resistance is measured in .
4. The unit for power is the .
5. A circuit has a voltage of 12V and a resistance of 4Ω. What is the current flowing through the circuit?
6. If a device draws 2A of current from a 120V supply, what is its resistance?
Use the circuit diagram below to answer the following questions.
7. If the battery provides 9V and the bulb has a resistance of 3Ω, calculate the current flowing through the circuit.
8. What is the power consumed by the bulb in question 7?
9. In a series circuit, the total resistance is the sum of individual resistances.
True
False
10. Which of the following is the correct formula for calculating electrical power?
P = I / V
P = V × I
P = V + I
P = V - I
