• Second-order circuit only.

• First-order circuit only.

• None of these.

The characteristic equation of a 2nd-order circuit is determined by?

• The specific form of the source(s)

• All electrical elements, such as resistors, capacitors, etc.

• Electrical elements such as resistors, capacitors, and inductors, except sources.

• Natural response.

• Forced response.

Which one do the initial conditions of a 2nd-order circuit satisfy?

• Once

• Twice

• Thrice

• None of these

What do the characteristic roots determine?

• The formats of both the natural and forced responses.

• The formats of both the natural and complete responses.

What chacteristics does a parallel RLC circuit most likely present if the resistance R is great?

• Overdamped

• Critically damped

• Underdamped

• None of these

Which one below is wrong?

• Series RLC circuits also have a chateristic equation whose roots are determined by R, L, and C values.

• Resonant frequency omega_0 does not hinge on resistance R.

• Switching on or off the source(s) of a 2nd-order circuit does not change the characteristics of the circuit.

• The number of initial conditions possibly available is the same as the order of the circuit equation.

The answer for Part (a) the last in-class example?

• 2*e^(-3*t) + 4*e^(-t) - 8

• 6*e^(-3*t) + 4*t*e^(-3*t) - 8
