Answer the following statement(s) true (T) or false (F)

1. Nearly all commercial, industrial, and residential power circuits are connected in parallel. 2. The total (line) current for an ac parallel circuit may not be equal to the arithmetic sum of the current in each of the branch circuits. 3. The power factor of the circuit is found by the use of the expression: PF = P + VI. 4. The apparent power or volt-amperes of the circuit can be determined by multiplying the applied voltage by the total current. 5. The amount of reactive power or VARs (volt-amperes-reactive) can be determined using the formula: VARs = P/VA.
