Answer the following statement(s) true (T) or false (F)
1. In an AC parallel circuit with capacitive and resistive branches, the total or line current is equal to the arithmetic sum of the currents taken by the individual branches. 2. For parallel circuits with unequal reactances where the capacitive current is greater than the inductive current, the total current lags the line voltage. 3. For a resonant parallel circuit, the line current is in phase with the line voltage 4. For parallel circuits with unequal reactances where the capacitive current is less than the inductive current, the total current lags the line voltage.
