Question

I think this is the right place to ask a question relating to basic elements and phasors (el-studies) :)

Answer 1

Okay, so I have this curcuit with this info:
\[v_{1}=141,4\sin(2513t) V\]
\[i=50\sqrt{2}\sin(2513-68,8^{o})\]
(see attached picture for circuit)
and I need to find
a) The voltage across the inductor in polar form.
b) The value of the inductor(inductance) and the power that's being used by it.
c) v_2(t) and draw a diagram for the circuit

Answer 2

Would it be right to do this:
\[V _{m}=I _{m}X _{L}=(50\sqrt{2} / 0^{o})(4/90^{o})\]
the / didn't come out right :P

Answer 3

v_1 is actually e_1 in the sketch :P
