Ampere increases when motor runs in shut off head.
Ampere is the measure of electrical current.
Shut off head is the maximum head that a pump can generate.
When the motor runs in shut off head, it experiences maximum resistance, causing the current to increase.
Ampere decreases because current flow is directly proportional to current.
Current flow and amperage are directly related.
As current flow decreases, amperage decreases.
Ohm's Law states that amperage is equal to voltage divided by resistance.
