An AC voltage can be expressed as v(t) = 120sin(100t + 45°). Represent this voltage as a phasor and calculate its RMS value.
💡 Hint: Use the known relationship between peak and RMS values.
If a resistor has an impedance of Z = 4 + 3j, calculate the total circuit impedance when 2 mH inductor is added in series at 60 Hz.
💡 Hint: Remember to incorporate both the resistive and reactive components.
