Which of the following is TRUE in case of the admittance of a circuit?...
It is the measure of flow of current which is allowed by the circuit.
Key Points:
Admittance (Y) is the measurement quantity that tells us how easily a conducting device can allow the flow of current through it.
Admittance can be defined as a reciprocal of impedance (Z). i.e Y = 1/Z
Admittance measures the flow of current allowed by the circuit which is the inverse of the impedance function.
Which of the following is TRUE in case of the admittance of a circuit?...
Admittance of a Circuit
Introduction:
The admittance of a circuit refers to the measure of the flow of current that is allowed by the circuit. It is the reciprocal of impedance and is denoted by the symbol 'Y'. Admittance is a complex quantity that includes both magnitude and phase.
Explanation:
The given options are:
a) It is the measure of flow of current which is allowed by the circuit.
b) It is the measure of voltage supplied to the circuit.
c) It is the measure of the resistance offered by the circuit.
d) It is the measure of the power dissipated in the circuit.
Option A: It is the measure of flow of current which is allowed by the circuit.
This option is correct. Admittance is indeed the measure of the flow of current allowed by the circuit. It indicates how easily the circuit allows the flow of current. A higher admittance value indicates a greater ease for current flow, while a lower admittance value indicates a higher resistance or impedance.
Option B: It is the measure of voltage supplied to the circuit.
This option is incorrect. The measure of the voltage supplied to the circuit is not related to admittance. Voltage is measured in volts and is the potential difference across the circuit or its components.
Option C: It is the measure of the resistance offered by the circuit.
This option is incorrect. The measure of resistance is different from admittance. Resistance is the opposition to the flow of current in a circuit and is measured in ohms. Admittance, on the other hand, measures the ease or allowance of current flow.
Option D: It is the measure of the power dissipated in the circuit.
This option is incorrect. Admittance is not directly related to the measure of power dissipated in the circuit. Power dissipation is determined by factors such as resistance, current, and voltage in the circuit.
Conclusion:
In conclusion, the correct statement regarding admittance of a circuit is that it is the measure of the flow of current allowed by the circuit. It indicates the ease or allowance of current flow and is not related to voltage, resistance, or power dissipation.
