1)The resistance of a resistor is 9.6 Ohms and the resistance of a coil is 5.5 O

Question

1)The resistance of a resistor is 9.6 Ohms and the resistance of a coil is 5.5 Ohms (Both of these values were measured with an ohmmeter.) What is the resistance of the circuit when driven at its resonant frequency?

2)What is the highest when a circuit is driven at its reasonant frequency as compared to when it is driven at any other frequency?

(To answer: type one of the following choices exactly as shown:
Impedance, Current, XL, XC,
Linear Frequency, Angular Frequency,

3)4. Given ? = 1340 [rad s-1], what is the linear frequency?

Explanation / Answer

1. resistance of the circuit when driven at its resonant frequency= 9.6+5.5=15.1 ohm

2. resistance will be higher when it is driven at any other frequency other than resonance frequency

3. f=  1340 /(2*pi )= 213.27Hz
