5 ASVAB-style practice questions
Open a question to review the choices, correct answer, and a short explanation.
Q1A circuit has 24 volts across a resistance and carries 6 amperes. What is the resistance?View question and answer
- 6 ohms
- 4 ohms
- 18 ohms
- 144 ohms
Correct answerB. 4 ohms
Why: Using R = V ÷ I, resistance = 24 ÷ 6 = 4 ohms.
Q2In a parallel circuit, the voltage across each branch is:View question and answer
- Always zero
- Added to the other branch voltages
- The same as the source voltage
- Inversely proportional to wire length only
Correct answerC. The same as the source voltage
Why: Every parallel branch connects across the same two nodes, so each branch has the source voltage across it.
Q3Which component is designed primarily to allow current flow in one direction?View question and answer
- Capacitor
- Fuse
- Transformer
- Diode
Correct answerD. Diode
Why: A diode conducts readily when forward biased and blocks most current when reverse biased.
Q4An ideal step-up transformer increases voltage and:View question and answer
- Decreases current
- Increases current by the same ratio
- Leaves current unchanged
- Changes the AC output to DC
Correct answerA. Decreases current
Why: With power approximately conserved in an ideal transformer, an increase in voltage corresponds to a decrease in current.
Q5To measure current through a resistor, an ammeter should be connected:View question and answer
- In parallel across the power source
- In series with the resistor
- Across an open switch only
- Without opening the circuit path
Correct answerB. In series with the resistor
Why: An ammeter must be placed in series so the current being measured flows through the meter.
