Thread: complex numbers

the potential difference across a circuit is given by the complex number
V = 40 + j35 volts

& the current is given by the complex number
I = 6 + j3 amps

How do i find the phase difference (the angle) between the phasors for Voltage V and Current I?

Convert the voltage and current from cartesian coordinates - where is the real value and the imaginary - to polar coordinates of the form . The phase angle is the difference between the two values of .

thanks for that just figured it out but good to double check
