Exercise : RL Circuits - True or False
- RL Circuits - General Questions
- RL Circuits - True or False
1.
Total current in an RL circuit always lags the source voltage.
2.
The resistor voltage in an RL circuit is always out of phase with the current.
3.
A filter passes certain frequencies and rejects others.
Answer: Option
Explanation:
Filters that are designed to remove certain frequencies and allow others.
Band- pass filter - only frequencies in a frequency band are passed.
Notch filter - rejects just one specific frequency.
4.
The power factor indicates how much of the apparent power is reactive power.
5.
A power factor of 1 indicates a purely reactive circuit, and a power factor of 0 indicates a purely resistive circuit.
