What is the unit of electrical resistance?
Answer: Ohm
Resistance is measured in ohms (Ω), named after Georg Simon Ohm.
According to Ohm's Law, if voltage is 24V and resistance is 6Ω, what is the current?
Answer: 4A
Using Ohm's Law (I = V/R), 24V ÷ 6Ω = 4 amperes.
Which type of circuit has all components connected end-to-end in a single path?
Answer: Series circuit
In a series circuit, current follows one continuous path through all components.
What happens to total resistance when resistors are connected in parallel?
Answer: It decreases
Adding resistors in parallel provides additional current paths, which decreases total resistance.
What is the power consumed by a circuit with 2A of current and 12V applied?
Answer: 24W
Power (P) = Voltage × Current = 12V × 2A = 24 watts.
In aircraft DC systems, which wire color typically indicates a ground return?
Answer: Black or bare
In aircraft wiring, black or bare/uninsulated wires typically designate ground returns per MIL-W-5088 standards.
