Electrical current alone has no heating effect. Current through a device, with a voltage across the device will have a heating effect. The equation for calculating it is power = voltage x current, where power is proportional to the heating effect If the AC supply is measured as an RMS voltage and an RMS current and the device is resistive, then the heating effect will be identical to the same values with a DC supply. RMS means the "average" voltage or current of an AC supply whereas the peak AC voltage refers to the highest voltage that is reached on each cycle. However, if the device is not just resistive but is inductive, the heating effect will be lower with an AC supply than with a DC supply. By inductive, we mean that the device has a coil or capacitor, for example, in the circuit. The reasons why are outside the scope of this answer but are explained in many electronics text books, or look up "power factor" on google

The answer depends on the sign of the growth factor which is less than 1. There is no factor that is "less then 1"!If the first term is 0, the growth factor has no effect.A positive growth factor less than 1 results in a sequence that decreases towards 0. A growth factor greater than 1 results in a sequence that increases without limit if the initial value is positive, or decreases without limit (towards minus infinity) if the first term is negative.

The variable that the investigator changes or manipulates during the experiment is called the independent variable. This is the factor that is deliberately altered in order to observe its effect on the dependent variable, which is the outcome being measured.

No, but power factor may affect the choice of a conductor's thickness! The whole point of power-factor correction is to reduce the load current in order to enable conductors of lower cross-sectional area to supply a given load.

An independent variable is the factor that is manipulated or changed by the researcher in an experiment to observe its effect on the dependent variable. It is the variable that is thought to cause a change in the dependent variable.

When the effect of one factor depends on the presence of another factor, outcomes are said to reflect an interaction effect. This means that the relationship between the two factors is not additive; instead, the impact of one factor changes depending on the level of the other factor.
