Transient Response

In an R-C circuit where the capacitor has an initial voltage of V₀, when the switch is closed, the response ____________

• Capacitor voltage becomes zero intantly

• decays with time

• rises with time

• first increases and then decreases

The value of the time constant in the R-L circuit is?

• L

• R

• L/R

• R/L

If the roots of an equation are real and unequal, then the response will be?

• critically damped

• damped

• under damped

• over damped

If the value of C in a series RLC circuit is decreased, the resonant frequency

• Increases

• Decreases

• Remains same

• Data not sufficient

An RC circuit has R = 2  and C = 4 F. The time

for the initial voltage to reach 66% of it initial value is:

• 2 s

• 8 s

• 4 s

• 2 s
