$begingroup$ The very nature of a resistor causes it to dissipate energy in the form of heat when attached to a power source. But if you connect a device to a power source through a resistor you can regulate the current through the device this way. However, semi-conductor based current regulators do a much better job. $endgroup$ –

Pump water from a storage tank to another storage tank and reverse the pump when one gets too full. Charge some batteries, or electric vehicles. An air conditioner, heat pump, or refrigerator could eat a lot of power, though you might consider pumping heat from one place to another generating heat, but again you need to pick your poison.
So, Energy dissipated by the conductor when Q Charge passes through the ideal conductor connected between a potential difference of V Volt must be equal to the Energy supplied by the battery to the conductor which is equal to QV. (NOTE: In case of Resistance also, the same amount of energy is dissipated.

Do not compact the storage piles, thereby enhancing natural air flow through the pile and assisting heat dissipation and decreasing biological action. As a side effect of dry fibre loss, the ash content rises when expressed as a percentage of the dry fibre left, as the amount of non-organic material in the fuel is not affected by microbial action.
When a coulomb drops through a volt, it loses potential energy 1 joule. This energy is dissipated as heat.
