The amount of current passed through the water of an electrode boiler depends on the:

The amount of current passed through the water of an electrode boiler is fundamentally influenced by the depth of the electrodes in the water. In an electrode boiler, electric current is conducted through the water, which serves as a medium for heat generation. The depth to which the electrodes are submerged affects the surface area available for current flow. A greater depth allows for more water to contact the electrodes, which increases the effective area for conduction. This can lead to a higher current flow, assuming the voltage remains constant.

The operational principles of electrode boilers hinge on the relationship between current, voltage, and resistance in the water. The resistance between the electrodes and the water is influenced by how deeply they are immersed; more depth can enhance the conductivity path due to the larger volume of water engaged, thereby allowing more current to pass.

Other factors such as voltage settings and control settings can affect the operation and efficiency of an electrode boiler, but the immediate determinant of current flow in the water is primarily the depth of the electrodes.
