The rectangular form of a coordinate is represented by
The polar form of a coordinate is represented by
where,
Calculation
Given, Voltage = 230∠60°
Z = 10 + j10 Ω = 10√2∠45°
I = 16.3∠15°
The voltage phasor is 230∠60° and current phasor is 16.3∠15°. Taking the voltage as the reference, the current will lag the voltage by 45 degrees with an amplitude of 16.3 Amp.
