## Homework Statement

A parallel RLC circuit with every component in parallel.

The resistance is 120 Ohm, the reactanse over the capacitor is 150 Ohm and the reactanse over the inductor is 70 Ohm. The total current is equal to 100mA.

Calculate the current passing through the inductance.

## The Attempt at a Solution

I have been searching the web for equations to calculate the total impedance of a parallel RLC.

I am not familiar with the names of inverse resistance and inverse reactance so they will be written as 1/R.

I found one equation saying...

(1/Z)^2=(1/R)^2+(1/XL-1/XC)^2

By using that equation , I calculated the total impedance. Then by using the total current calculated the Power source voltage. Which equals 8.9 V, then via Ohms law came to the conclusion that the current through the inductance is equal to 127mA.

This result works wery well with the right angle triangle, using the Pyth. Teorem.

The paper we got says that the current should equal 9.5mA, have I done something wrong?

Some places I just see the equation

1/Z=1/R+1/XL-1/XC

Are both correct?

Many thanks in advance!
