Answer the following statement(s) true (T) or false (F)
1. Admittance is the inverse, or reciprocal, of impedance. 2. Admittance is indicated by the letter S. 3. The relationship between admittance, in siemens, and the impedance, in ohms, is Y=1/Z. 4. Conductance, unlike admittance, is measured in siemens. 5. The relationship between the admittance, the conductance, and the susceptance is the same as the relationship between the impedance, the resistance, and the reactance.
