Do you mean drawing a phasor diagram makes it easier? Could you explain that last statement a little more if you get time...thanks.

I knew that about the capacitor...I was unaware you could manipulate the impedance expression like that but it makes sense since there is no capacitor! Thank you so much for your help...so much.

Here's a tricky one... A resistor is in series with an inductor, with the current (I) lagging behind the voltage (V) by 60degrees. I am given the impedance (Z) of the circuit, which is 350ohms. How the heck can I find the resistance (R) and the inductive reactance (XL) when I know only the...

Thank you for your help. I was making it waay to hard.

Wow. Your way is waay easier to understand! Like I said at the beginning, I was making it a lot harder than it really was. Using a square diagram to draw the components I was completely screwing up which direction they were going. As I reread my last post and look at my diagrm...I don't know...

If both charges on opposite sides of the diagonal were positive you would have one charge pointing in the -x, -y direction and one pointing in the +x, +y direction. So those two would cancel each other out. The other charge (on the diagonal) is a length = sq.root(a^2+b^2) away from the empty...

So if those two charges cancel each other out...you would have a zero electric field at one corner and a ? charge at the other...

They would be opposite in order to cancel each other out...

Ok...so in order for the signs to cancel each other out you need at least one sign that was negative...since the field at the empty corner (q4) of the square is the vector sum of the fields due to q1, q2, and q3. And since each of the charges is equidistant from each other and the signs are...

Wow...then I am really confused. Could you shed some light on that for me? (Thanks for your response!)

I'm pretty sure I'm making this question a lot harder than it is... The question is this - "Three point charges are fixed to the corners of a square, one to a corner, in such a way that the net electric field at the empty corner is zero. Do these charges all have the same sign or the same...

Please Help! I would really appreciate some help on this one...I'm pretty sure I'm making it harder than it is... The question is this - "Three point charges are fixed to the corners of a square, one to a corner, in such a way that the net electric field at the empty corner is zero. Do...
