BEE Electric Circuit Analysis 3

Question 1

Norton's theorem converts a circuit to an equivalent:

Accepted Answer

Current source in parallel with Rth

Answer

Norton's equivalent consists of a short-circuit current source (IN) in parallel with the Thevenin resistance (Rth).

Question 2

In mesh analysis, mesh currents are defined to flow in which direction by convention?

Accepted Answer

Clockwise

Answer

By convention, mesh currents are assigned to flow clockwise in each mesh, though counter-clockwise is also valid if consistently applied.

Question 3

A 10 Ω resistor carries 2 A. What power does it dissipate?

Accepted Answer

40 W

Answer

P = I²R = (2)² × 10 = 40 W.

Question 4

Which of the following is the correct expression for the quality factor Q of a series RLC circuit?

Accepted Answer

Q = ωL/R

Answer

For a series RLC circuit, Q = ωₒL/R = (1/R)√(L/C), indicating the sharpness of resonance.

Question 5

KVL (Kirchhoff's Voltage Law) is based on the principle of conservation of:

Accepted Answer

Energy

Answer

KVL states that the algebraic sum of voltages around any closed loop is zero, which is a direct consequence of energy conservation.
