A 46 m H inductive coil has a resistance of 10 ohm. How much current will it draw, if connected across 100 V, 50 Hz source? To determine the value of capacitance that must be connected across the coil to make the power factor ofthe circuit to he unity.
Answers
Answer:
Given : f=1000 Hz
Resistance of inductive coil X L =100Ω
Thus inductance of coil L= 2πfXL
∴ L= 2π×1000100 = 20π1 Henry
Answer:
The value of capacitance is 20π1 Henry
Explanation:
How to calculate the value of capacitance?
The capacity of a component or circuit to gather and hold energy in the form of an electrical charge is known as capacitance. Devices that store energy include capacitors, which come in a variety of sizes and forms.
A material thing or device's capacitance is its ability to hold electric charge. The ratio of those two values is used to calculate the change in charge in response to an alteration in electric potential.
C=QV is the formula for capacitance. Therefore, a system's capacitance serves as a gauge for how much charge it can hold when subjected to a specific potential difference.
Given : f=1000 Hz
Resistance of inductive coil X L =100Ω
Thus inductance of coil L= 2πfXL
∴ L= 2π×1000100 = 20π1 Henry
Therefore the value of capacitance that must be connected across the coil to make the power factor of the circuit to he unity 20π1 Henry
