Free ASVAB Exam Questions That Helps Candidates Pass

Comprehensive and Detailed Explanation:

In a series circuit, resistances add directly: R_total = 3 Ω + 9 Ω = 12 Ω. Ohm’s law states I = V/R. With V = 12 V and R_total = 12 Ω, the current I = 12/12 = 1.00 A. Choice C is correct. A common mistake is to treat series like parallel and compute reciprocals; that would be incorrect here. Remember: series → same current through each component; parallel → same voltage across each branch. If this were parallel, equivalent resistance would be less than the smallest branch, but in series it must be greater than any single resistor. The EI subtest often tests recognition of series vs. parallel characteristics and application of Ohm’s law (V = IR), power (P = VI), and basic component behavior. Write out what’s given, verify the configuration, and compute in the correct sequence to avoid traps.

“Reluctant” = hesitant or unwilling. Opposite of willing. Happy and strong are unrelated. WK often checks synonyms/opposites for everyday words.

A transistor acts as an amplifier or switch in circuits. Capacitors store energy, ohmmeters measure resistance, rectifiers convert AC to DC. EI questions often check knowledge of modern circuit components.
