Which quantity is defined by volts times amps times power factor?

Real power is what you’re getting when you account for how efficiently a circuit uses energy. In AC circuits, the real power P equals the voltage V times the current I times the power factor pf: P = V × I × pf. The product V × I is the apparent power (in volt-amperes), and multiplying by the power factor (which ranges from 0 to 1 and reflects how much of that current actually does useful work) gives the actual power you’re consuming, measured in watts. So volts × amps × power factor defines real power.

Volt is just potential difference, ampere is current, ampere-hour is a measure of charge over time, and hertz is frequency—none of those incorporate the power factor, so they don’t match the expression.
