L=4H, R=20
L=8H, R=20
Answers
Answer:
The Correct Answer is Option a L=1H, R=2Q
Answer:
Concept :
The obstruction to current flow in an electrical circuit is measured by resistance. The Greek letter omega () represents the unit of measurement for resistance, known as ohms. The name of the unit of resistance is derived from Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current, and resistance. He is credited with creating Ohm's Law.

Answer:
The correct option is [A]. L=1H, R=2Q
The time constant, commonly represented by the Greek letter tau, is the parameter that describes how a first-order, linear time-invariant (LTI) system responds to a step input in physics and engineering. [1] [note 1] The primary characteristic of a first-order LTI system is the time constant.In the time domain, the impulse response to a Dirac delta function input or the step response to a step input are typically used to examine the time response.
A first-order time-invariant system's bandwidth, or the frequency at which the output signal power is greatest, is also determined by the time constant in the frequency domain (for instance, by examining the Fourier transform of the step response or using an input that is a straightforward sinusoidal function of time).
