Even @2000W it would need some time to increase the water temperature. But the contact resistance to the battery might be a problem. WebFeb 25, 2024 · An 8 ohm dummy load is much more resistant to abuse than a paper/polypropylene speaker cone. Adjustable electronic loads are for playing with batteries and power supplies, they are worse than useless as load simulators for LF amplifiers. Often they'll have next to no control loop gain above a few thousand or 10s of thousands Hertz.
