Why power factor is not present in direct current?

Updated: 8/11/2023

There is no angular gap between voltage & current in Direct Current. So power factor is always cos 0 deg. i.e. 1 for all tha cases of DC.

There's no fun in playing it safe. Why not try something a little unhinged?

Lightning carries Alternating current or Direct Current?

Power lines carry electricity as alternating current.

Is it true that the current supply from electric power generating plants is an alternating current?

Yes, it is true that current supply from generating plants is an alternating current. There is no success found in bulk power generation of direct current ( D.C. ) in a power plant. But yes it is possible to transmit the power in the form of direct current ( High Voltage Direct Current Transmission-HVDC Transmission ) that possible after converting the generated alternating current into direct current with the help of high range converters.

What is the relationship between voltage power and current?

The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V

What is power factor of resistor?

A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.

Can you generate direct current?

Direct current can be generated by a generator. Generators are not as efficient as alternators ( that generated AC power ). Vehicles use direct current but come equipped with alternators. The AC power is rectified ( changed to DC ) for use.

Is it possible to measure power factor for dc system?

noAnswer'Power factor' is a quantity associated with alternating-current systems, and does not apply to direct-current systems'.

What is one horse power equal to in direct current?

1 horse power is equal to 746.0014 Watts of direct current.

If we increase the current then what about the power factor?

The power factor depends on the phase angle between the voltage and current on a conductor. The amplitude of the current has no effect on it.

Lightning carries Alternating current or Direct Current?

Power lines carry electricity as alternating current.

How does an ac power source differ from a dc power source?

AC power sources are the adapter power sources. DC power sources are the direct power sources. DC stands for direct current, meaning it is a direct source of energy., and AC stands for alternating current, which means it is a secondary source of power.

What IS AC power and DC power?

AC Power is Alternating Current whereas DC Power is Direct Current.

What type of current does a laptop's power adapter produce?

Direct current

Is current reduces with increase in powerfactor?

If power factor is increased, current will be reduced for a specific real power (kWs) relative to before. Total power is real power plus the vector of reactive power (you have to do polar math). So total current = (current from real power) + (current from reactive power). By changing the power factor, you decrease the second quantity. Go to Wikipedia.com and search for Power Factor if you need a more extensive description.
