Question 697149: The potential difference across a circuit is given by the complex number
V = 40 + j35 volts
and the current is given by the complex number
I = 6 + j3 amps
a) sketch the appropriate phasors on an Argand diagram.
b) find the phase difference (i.e. the angle Φ )between the phasors for voltage
V and the current I.
c) Find the power (watts) given that P = V x I x cos Φ
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
V = 40 + j35 volts and I = 6 + j3 amps
a) sketch the appropriate phasors on an Argand diagram.

b) find the phase difference
The angle between the voltage V and the real, x-axis can be found from
--> radians (rounded)
The angle between the current I and the real, x-axis can be found from
--> radians (rounded)
We can calculate very close approximations of and
radians (approx in degrees)
(rounded)

c) Find the power (watts) given that P = V x I x cos Φ
The magnitudes of V and I are
(rounded)
(rounded)
watt
