Ohm's law: Current = voltage divided by resistance
240 volts divided by 0.2 ohms = 4,800 amperes.
1,152,000 watts, by the way, so don't even think about trying it.
1.1 amps
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
That is the resistance, measured in ohms.
One ohm is the resistance through which a current of one ampere will induce an electrical potential difference of one volt. Ohm's Law: Resistance is Voltage divided by Current
current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
No.
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
Resistance (Ohms) = Potential Difference (Voltage) / Current (Amps)
Assuming you are asking "How does resistance altercurrent?", then the answer is that, for a given value of potential difference, the current is inversely-proportional to the resistance. E.g. doubling the resistance will reduce the current by half.
some resistance and potential difference
I don't no
resistance of a material
That is the resistance, measured in ohms.
current is produced when there exists a potential difference between two points and d electrons move between these points.
That's Ohm's law. Volts = Current (or Amps) * Resistance.http://en.wikipedia.org/wiki/Ohms_law
