L, E and i: 50.0mH Inductor and 24.0V AC Voltage Source

Click For Summary

Homework Help Overview

The discussion revolves around a circuit involving a 50.0 mH inductor connected to a 24.0 V AC voltage source, with a current of 0.60 A flowing through it. Participants are exploring the relationship between inductance, voltage, current, and frequency in the context of AC circuits.

Discussion Character

  • Exploratory, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants discuss the formula for frequency in relation to angular frequency and impedance. There are attempts to connect the concepts of voltage, current, and impedance, with questions about how to incorporate inductance into their reasoning.

Discussion Status

The discussion is active, with participants building on each other's ideas regarding the relationships between voltage, current, and impedance. Some guidance has been offered about considering impedance in their calculations, but there is no explicit consensus on the final approach.

Contextual Notes

Participants are working under the constraints of a homework problem, which may limit the information available for discussion. There is an emphasis on using the relationships between L, E, and i without providing a complete solution.

A 50.0mh inductor is connected to an ac voltage source of 24.0V.The current flowing in this circuit is 0.60A.The frequency of the voltage source is :
a)50Hz
b)60Hz
c)1.27*10^3 Hz

My Work so far ! :
f = w/2pi.

But here we have L , E and i.

Any help will be welcomed.

You can do better than this. How will you bring in L, E and i? Think impedance.

So,impedance is : z=Lw = L*2pi*f ...

A guess , z = V/I = E/i ! but V(max)/I(max)

If z = V/I, can you relate ω to V and I?

So is it , V/I=Lw then V/LI=w=2pi*f .
 
Correct.

Correct.

Thank you, kuruman.
