Question

If the admittance of a parallel a.c. circuit is increased, the circuit current 
A. remains constant

B. is decreased

C. is increased

D. none of the above

​

Answer 1

Answer:

Explanation: c

Answer 2

The correct answer is option (C.) is increased.

Explanation:

• If the admittance of a parallel a.c. circuit is increased, the circuit current is increased.
• Admittance is the Reciprocal of the impedance.
• In electrical engineering, admittance is a measure of how easily a circuit or device will allow a current to flow.
• It is defined as the reciprocal of impedance, analogous to how conductance & resistance are defined.
• Admittance is defined as a measure of how easily a circuit or device will allow current to flow through it.
• In an AC circuit; in addition to the resistance, two impeding mechanisms (inductance and capacitance) have to be considered.
