What is the phase angle between the voltage across and the current through a series RLC circuit if XC is 25 ohms, R is 100 ohms, and XL is 75 ohms?
27 degrees with the voltage lagging the current
27 degrees with the voltage leading the current✓Respuesta correcta
63 degrees with the voltage lagging the current
63 degrees with the voltage leading the current
Explicación
Here the inductive reactance exceeds the capacitive reactance, leaving a net reactance of +50 Ω, so the circuit is inductive. The arctangent of 50/100 is about 27°, and in an inductive circuit the voltage leads the current.
