Ohm's Law defines the relationship between voltage and current in a resistive circuit.
Other circuit configurations can be used with the same format, if the capacitance and/or inductance of the circuit is translated into an equivalent impedance first.
Commercially, this allows utilities and power generation facilities to both estimate the required demand of the consumers attached to their network, as well as estimate (and therefore account for) the losses in transmission. In conjunction with appropriate metering equipment, it gives them a measurable quantity to "charge for", thereby making money on the supply of power.
It's also a pretty useful relationship to know when developing power-consuming devices; this means one can estimate the "cost" of operation based on the local utility rate(s).
When used with Faraday's Law, Coulomb's Law, and Maxwell's Equations, there's nothing in electrical theory that cannot be modelled in some fashion - which is good news for software designers.

Ohms law is used in the design of electronic circuits.
The commercial application would be in selling those circuits or selling the service of creating a circuit.

There are to many to list. But here are a few.
A motor need a certain size wire, so using a number of electrical engineer equations you can determine the correct size wire.
The feeder to your house was sized to carry the load. Power = Volts x Current. Most homes use 100 amp or 200 amp main feeders. It goes on and on.
