Aretha measures a circuit at 110 v and 240 . using ohm’s law, what can she calculate for the circuit? voltage ohms resistance current

Ohm's law deals with the relation between voltage and current in an ideal conductor. It states that: Potential difference across a conductor is proportional to the current that pass through it. It is expressed as V=IR. The answer most likely would be resistance or current. It depends on what is the unit of the 240 value. If it is ampere then we can calculate for the resistance. However, when 240 is in units of ohms then we can calculate the current.
