Admittance is defined as a measure of how easily a circuit or device will allow current to flow through it.
Admittance is the reciprocal (inverse) of impedance, akin to how conductance and resistance are related.
In parallel circuits to calculate equivalent admittance conductance and susceptance are added.
For parallel RL circuit equivalent admittance;
Y = G - jB
where;
Y → Admittance (1/Z)
G→ Conductance(1/R)
B→ Susceptance (1/ωL)
Analysis:
If;
Frequency (f) of applied voltage decreases → ω↓ → XL↓ → B↑ → Y↓→ Z↑
