BEE Fundamental Circuit Analysis 2

Question 1

A current source of 5 A is connected in parallel with a 10 Ω resistor. What is the voltage across the resistor?

Accepted Answer

50 V

Answer

Using Ohm's law, V = I × R = 5 A × 10 Ω = 50 V.

Question 2

Which theorem states that any linear two-terminal network can be replaced by an equivalent voltage source in series with an impedance?

Accepted Answer

Thevenin's Theorem

Answer

Thevenin's Theorem replaces a complex linear network with a single voltage source (V_th) in series with a resistance (R_th).

Question 3

In a series RLC circuit at resonance, which statement is TRUE?

Accepted Answer

Inductive reactance equals capacitive reactance

Answer

At resonance, X_L = X_C, causing the imaginary parts to cancel and impedance to be purely resistive (minimum).

Question 4

Three resistors of 6 Ω, 3 Ω, and 2 Ω are connected in parallel. What is the equivalent resistance?

Accepted Answer

1 Ω

Answer

1/R_eq = 1/6 + 1/3 + 1/2 = 1/6 + 2/6 + 3/6 = 1, so R_eq = 1 Ω.

Question 5

According to the Superposition Theorem, when analyzing a circuit with multiple independent sources, you:

Accepted Answer

Activate one source at a time, deactivating others by replacing voltage sources with short circuits and current sources with open circuits

Answer

Superposition requires solving for each independent source alone, then summing all individual contributions.
