# As voltage decreses, amps decrease. opposite of Ohm's law. How ?

M

#### Manuel

Situation - A three phase generator connected to a 3 phase, resistive load bank.
As we decrease output voltage, amps drawn by load also decrease.
Hertz remain constant.

Why ?

J

#### Joe E.

V = I*R
If V goes down while R remains constant, I has to go down, too.

R

#### Robert Scott

This is exactly Ohm's Law behaving properly.

#### PhilCorso

Manuel... the response you observed is correct for a resistive load because I = V/R!

If a constant kVA load, like a running motor, then the current increases as voltage decreases, and vice-versa.

K

because according to ohm's law i depend v. So if we decrease the voltage current automatically decreases.

You mean stand alone generator or generator with prime mover?

A

#### A Brown

I thought Ohm's law stated
E=IR so I= E/R, but not E=I/R

I believe he was referring to the math in the equations, not the assigned letters.
