As frequency decreases in a parallel RL circuit the impedance also decreases.

More Questions from RL Circuits

• The current lags the source voltage in a series RL circuit.
• The circuit in the given circuit is a low-pass filter.
• The impedance of the circuit in the given circuit is 110 Ω .
• If Y = 20 mS, then Z = 20.
• For series ac circuits containing both resistance and inductive reactance, total opposition to current can be found by simply adding ohmic values or oppositions to current.
• If a 7.5 kΩ resistance is connected to a 10 kΩ inductive reactance in a series RL circuit, then the impedance equals 12.5 kΩ .
• In a series RL circuit, a power factor of 0.5 results in less energy conversion to heat than does a power factor of 0.6.
• Phase angle is the difference in phase between the applied voltage (VS) and the circuit current (IT).
• As the frequency increases in a series RL circuit the impedance also increases.
• The phase angle will increase in a parallel RL circuit if the resistance is increased.
