3. Electrical power that performs useful work and transfers energy across the system, represented as P.
5. The angular position of voltage at a location relative to a reference, represented as θ.
6. The electrical pressure that drives current and supports power transfer, represented as V.
7. The difference between voltage phase angles at two locations that drives real power transfer, represented as δ.
9. Unit for Real Power
10. Power that supports voltage by sustaining electric and magnetic fields needed for energy transfer, represented as Q.
12. The component of impedance that shapes AC power flow behavior by opposing changes in current or voltage without creating real heating losses.
13. The component of impedance that opposes current and causes real power losses and heating, represented by R.
14. The total opposition to current that determines how power distributes across the network, represented as Z.
15. Unit for Voltage
16. Unit for Current
