← In a phasor diagram the current phasor is drawn 90° behind the voltage phasor, measured against the sense of rotation. Which part is in the circuit?
A resistor carries the current i = 3.0 + 4.0 sin ω t, in A, a steady part together with an alternating part. What is the rms value of this current? →
