There's something wrong here. 3250 watts on 240 volts is only 13.5 amps, not 40. And that would be 12 gauge wire on a 20 amp circuit. But that seems low for an oven. If it truly is a 40 amp appliance then the gauge would be #8 wire. The wiring info that comes with the appliance should tell you everything you need to know.
Ohm's Law states Volts = Amps x Resistance. You would need to apply 600 volts across 3 ohm load to have 200 Amps flow in circuit. Not sure what you are really asking and why you mentioned 2 gauge.
The typical number of amps per circuit is 15 or 20. The typical number of volts that enter a home is 120/240 volts. The typical number of volts for each circuit is 120 volts. A GFCI (Ground Fault Circuit Interrupter) is a safety device that helps prevent electric shock by quickly disconnecting power when it detects a ground fault.
The voltage has nothing to do with the gauge of wire needed to supply a given circuit. The size wire is determined by the amperage of the overcurrent protection device (circuit breaker, etc.) being used to supply power to the circuit.
In a parallel circuit, Voltage is constant through out the circuit. Thus, the voltage across each lamp is 6-volts.
The total loaded 20 amp breaker operating on 120 volts will handle 2400 watts before it will trip. This is the maximum and the circuit wiring will probably get warm. De-rate to 80% capacity will bring the wattage down to 2400 x .8 = 1920 watts.
You use an "amp gauge" to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!

Reducing the current to a circuit causes a higher resistance -- assuming constant Volts. Also, reducing the current to a circuit causes lower Volts -- assuming constant resistance.AnswerAltering the current has absolutely no effect on a circuit's resistance. Reducing the current will reduce line losses (I2R) and reduce the voltage drop along a conductor.

30 amps.
The relationship between volts and amps in an electrical circuit is defined by Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R) in the circuit. In other words, volts per amp is a measure of resistance in the circuit.
An 18 gauge wire can handle a maximum amperage of approximately 16.5 amps at 12 volts.
A circuit has an applied voltage of 100 volts and a resistance of 1000 ohms. The current flow in the circuit is 100v/1000ohms which would equal .1.
