What is effective AC resistance?
Answer: The resistance offered by a conductor for both AC and DC is different, the resistance offered 2 DC by conductor is known as DC resistance while the resistance offered to AC is known as AC resistance or effective resistance. For a given conductor AC resistance is more than its DC resistance.
Is resistance the same for AC and DC?
As we know that frequency in DC supply is zero, so there is no skin effect (a behavior of alternating current to flow through the surface i.e. outer layer of a conductor instead of the core of the wire). in DC circuits. Due to the skin effect, AC resistance are more in AC circuits than DC supply in DC circuits.
What does AC resistance mean?
: the ratio of the average power dissipated to the square of the effective current in a conductor carrying an alternating current.
What is the phase relation between current and voltage?
The current and voltage in an RLC circuit are related by V = IZ. The phase relationship between the current and voltage can be found from the vector diagram: its the angle between the impedance, Z, and the resistance, R. The angle can be found from: If the angle is positive, the voltage leads the current by that angle.
What if inductor is connected to DC?
When an Inductor is connected to a circuit with Direct Current (DC) source, two processes, which are called “storing” and “decaying” energy, will happen in specific conditions. The Inductor acts like an ordinary connecting wire, its Resistance is zero. The Current iL through an Inductor cannot change abruptly.
What is the difference between a capacitor and a resistor?
Basics of Capacitor and Resistor: A resistor is an electronic component used to resist the flow of current in a circuit. A capacitor, on the other hand, is an electronic component used to store electrical charge. It generally opposes changes in current in electrical and electronic circuits.
What is the purpose of a resistor on a capacitor?
Explanation: When capacitors and resistors are connected together the resistor resists the flow of current that can charge or discharge the capacitor. The larger the resistor , the slower the charge/discharge rate. The larger the capacitor , the slower the charge/discharge rate.
