Q: Which of the following statements best describes Ohm's Law?

The current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance. — Ohm's Law states V=IR, accurately described by option A.

Q: In a series circuit, if one resistor fails open (becomes infinite resistance), what happens to the current in the circuit?

The current goes to zero. — An open circuit results in infinite resistance, hence no current flow.

Q: What is the equivalent resistance of three resistors (R1 = 10 ohms, R2 = 20 ohms, and R3 = 30 ohms) connected in parallel?

1.67 ohms — 1/R_eq = 1/R1 + 1/R2 + 1/R3 -> R_eq = 1/ (1/10 + 1/20 + 1/30) = 1.67 ohms.

Q: Kirchhoff's Current Law (KCL) is based on the principle of conservation of:

Charge — KCL states the sum of currents entering a node equals the sum of currents leaving; based on charge conservation.

Q: What is the unit of measurement for electric power?

Watt (W) — Electric power is measured in Watts (W), where P = V*I
