Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following components is used to measure current in a circuit?
Voltmeter
Ammeter
Ohmmeter
Resistor
2. What is the relationship between voltage, current, and resistance in a circuit?
V = I/R
I = V*R
R = V*I
V = I*R
3. A series circuit has only one for current to flow.
4. In a parallel circuit, the voltage across each branch is .
5. The unit of electrical resistance is the .
6. Adding more resistors in series decreases the total resistance of the circuit.
True
False
7. An ammeter is connected in parallel to measure current.
True
False
8. Draw a simple series circuit containing a battery, two resistors, and an ammeter to measure the total current.
9. Calculate the total resistance of three resistors (10 Ω, 20 Ω, and 30 Ω) connected in series.
10. A parallel circuit has two resistors, 15 Ω and 25 Ω, connected to a 9V battery. Calculate the total current flowing from the battery.
