• negative

• zero

• positive

• infinity

Answer 1

In series LCR circuit for X_L > X_C, tan Φ will be positive.

Explanation:

In a series LCR circuit,

tan Φ = `(X_L - X_C)/R`

If X_L > X_C, then (X_L− X_C) is positive, so tan⁡ Φ is positive. The circuit behaves as an inductive circuit, and current lags behind voltage.
