Please why is the phase angle negative

[@SkanCityAcademy_SirJohn]

Mimi, whenever you want to find the phase angle, always use the values exact values of Xc, XL and R, don't use the absolute values. And since the circuit is capacitive its going to have a -jXc component. That's how come we got -j50

@@SkanCityAcademy_SirJohn thanks but how will you know if a circuit is capacitive

[@SkanCityAcademy_SirJohn]

@@efyanaomi-eh9wg okay, thats so simple, the circuit contains a capacitor, i.e 200/pi microfarad.

[@efyanaomi-eh9wg]

@@SkanCityAcademy_SirJohn so anytime a circuit contains a capacitor, the phase angle will negative?

[@nicklehman3984]

I'm lost on this one. I have never seen a capacitance value divided by pi in the reactance formula.

Please kindly state the time stamp so I can check and explain to you
