How is Wattless current obtained in AC circuit?
The electric current in an AC circuit is said to be Wattless Current when the average power consumed or dissipated in the given electrical circuit is equal to zero or null. In other words, the wattless current is produced only in an electrical circuit with a single capacitor or inductor.
How do you calculate Wattless current?
Originally Answered: What is meant by ‘wattless power’? It is calculated by the following formula: P = I·V·sinθ, where P is the power in watts, I is the current in amperes, V is the voltage in volts, and sinθ is the sine of the angular phase difference between the current and the voltage.
What do you meant by Wattless current?
Wattless Current in an AC circuit is when the average power consumed in such circuit corresponds to Zero. Such current is also called as Idle Current. The current in a.c. circuit is said to be wattles if the average power consumed in the circuit is zero.
Which circuit has a Wattless current flow?
Wattless Current can be defined as follows: if the average power used in such a circuit equals to Zero, the current in an AC circuit is said to be Wattless Current.
What is Wattless current in LCR circuit?
When the power dissipated or consumed is zero, the current is said to be wattless current or an idle current. This implies that the phase difference between the current and voltage should be π2.
How does current flow through a capacitor in an AC circuit?
CAPACITIVE AC CIRCUITS The capacitor is connected directly across the AC supply voltage. As the supply voltage increases and decreases, the capacitor charges and discharges with respect to this change. A current will flow through the circuit, first in one direction, then in the other.
How do you calculate current in a circuit?
If the voltage (V) and resistance (R) of any circuit is given we can use the current formula to calculate the current, i.e., I = V/R (amps).
How does current in a circuit work?
WHEN DOES CURRENT FLOW IN A CIRCUIT? Current only flows when a circuit is complete? when there are no gaps in it. In a complete circuit, the electrons flow from the negative terminal (connection) on the power source, through the connecting wires and components, such as bulbs, and back to the positive terminal.
How do you describe current in a circuit?
Current is the rate at which charge crosses a point on a circuit. A high current is the result of several coulombs of charge crossing over a cross section of a wire on a circuit. If the charge carriers are densely packed into the wire, then there does not have to be a high speed to have a high current.
What is the formula to be used in finding the current flow in the circuit?
FAQs on Current Formula If the voltage (V) and resistance (R) of any circuit is given we can use the current formula to calculate the current, i.e., I = V/R (amps).
What is power factor of Wattless current?
In a wattless current real power is zeron and hence power factor is zero.
