Frequency (AC)

[Ray]

Voltage is more than likely 100 volts in

Summed sine voltage would be 200v peak to peak.

Or if it says its a 200v input than peak to peak would be 400v ~

They are giving you everything you need to know to answer any question.

Current

Voltage

Loss to heat

Actual energy output

Freq

Phase angle is something i know about and how it works but not the math to figure it out.

Or, maybe i missed the actual real question here.

[Ray]

sorry ray, it is not, I have to find the circuit impedance, current flowing, potential difference across the resistor and inductor, and the phase angle between the voltage and current.

If you really know ohms law than you know the impedance, current

Im actually at the hospital or id figure out phase angle.

Break it do to the basics man.

Seems stupid simple to me.

[Ray]

Phase angle.

Fixed for the given freq

Then add for the slope of the circuit itself at that freq.

Take a pic or the actual question???

[IH8PunkRok]

Phase angle.

Fixed for the given freq

Then add for the slope of the circuit itself at that freq.

easy now dont want to scare people away lol

[Dubpower]

for the impedance I did this:

Z=Sqrt.*(R^2+(Xl-Xc)^2)

Z=Sqrt.*(100^2 + 628^2)

Z=636 ohms

current flow I did this:

R=V/I

R=200/2

R=100 ohms

Potential difference across the resistor and inductor:

?????????????????

The phase angle between the voltage and current:

Vin^2=Vr^2 + Vl^2

where Vl = I * Xl and Vr = I * R

I think that is the right formula

Take a pic or the actual question???

I will type it out for ya.

A coil consists of a resistance of 100 ohms and an inductance of 200 mH. if an alternating voltage v, given by v= 200sin500t volts is applied across the coil, calculate

(a) the circuit impedance

(d ) the current flowing

(c ) the potential difference across the resistor and inductor

(d) the phase angle between the voltage and the current

thanks for the help, sorry if I come across rude, I am not.

Iget 141ohm

100v

100v

1ohm

Your calculations are off.

Uhh.

What book are you working out of??

103?

[Ray]

Heres the worksheet from electronics 103

[Dubpower]

no book at all, just work sheets.

ah now I see it, I got the hole thing wrong. thanks for the help ray ya legend!
