To solve these types of problems, students should remember the formula of phase difference between current and applied voltage in a series lcr circuit. However, when you introduce inductance or capacitance, a phase shift occurs and the phase angle depends on the amount of inductive and capacative reactance.

As The Frequency Increases, The Inductive Reactance (X L) Increases, Which Causes The Phase Angle, Or Shift Between The Applied Voltage And Current, To Increase.

This phase difference is graphed below. I(t) = c dv dt = c(v 0 )cos t = i 0 cos t where: Phase difference between the applied voltage and resulting current.

Think about it, the voltage source is the reference. The voltage leads that of current by 90 o or in other words, voltage attains its maximum and zero value 90 o before the current attains it. Pure resistive loads do not cause any current phase shift.

If The Circuit Is Purely Resistive, The Phase Angle Is Zero, And The Power Factor Is 1.0

In simple words, a voltage is a potential difference between two points in an electric field that forces electrons to move in a particular direction in the circuit, and therefore, generate current. Thus, tanϕ = iri(x l. ∴ phase difference between the applied voltage and current, ϕ = 0°.
