What is the acceleration??????

mr Goodwill [35]

Answer: Acceleration is a measure of how fast velocity changes. Acceleration is the change of velocity divided by the change of time. Acceleration is a vector, and therefore includes both a size and a direction. In short, acceleration is the rate at which speed changes.

We think of the response of the circuit as the ratio of the maximum current to the maximum voltage provided. Explain why the rat

Answer:

Z = R, i = V/Z, w = √1 / LC

Explanation:

In an RLC circuit the impedance of the circuit is

Z = √[R² + ( $X_{L} - X_{C}$ )²

Where

$X_{L}$ = wL

X_{L} = 1 / wC

They are the reactances of the inductor and the capacitor, in this case the current advances to the voltage in the first and is delayed from the voltage in the second, so when the two values give the same reactance the current goes in phase with the voltage and the impedance is minimal

Z = R

V= i Z

i = V/Z

Therefore the current is maximum, this occurs when

w = √1 / LC

Saying that this is the resonant frequency
