1. ### Nodal voltages

Thanks its coming together now. so my current = 20/9.93 = 2A I don't understand how to get degrees yet \phi = tan^{-1}\frac{y}{x} do I take 8.3/5,5 tan and then use above formula? what is the -1 how do i use on calculator?
2. ### Nodal voltages

Here is a problem I got wrong, with the solution. I don't understand how they got answer. I don understand how you get 5.6 + j8.2 as 9.93 <55.67 how does 5.6 become 9.33 and j.2 = 55.67
3. ### Nodal voltages

I'm confused on how to get proper result I have now I = 20V <20 degree/ 5.6+J8.2 and I found in book the way to draw circuit. but I don't understand how to use the equation with cos and j 20 sin.
4. ### Nodal voltages

So if I need to find E/Z = 20/9.9 = 2A Now all I do is redraw circuit with 2A current source with impedance parallel in circuit?
5. ### Nodal voltages

Ok I'm reading that chapter now, I attached a sample I'm working on now.
6. ### Nodal voltages

Yea I was there today, will be back tomorrow.
7. ### Nodal voltages

Can someone direct me to a tutorial for solving network nodal voltages. Also need to learn how to convert voltage source to a current source.
8. ### 2KVA transformer how do I determine the max. safe primary current.

If I have 2KVA transformer how do I determine the max. safe primary current.
