Want this question answered?
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
Resistance (Ohms) = Potential Difference (Volts) / Current (Amps) So, 12/0.25 = 48 Ohms.
I don't no
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
You can apply a potential difference across a wire to cause a current to flow through. Ohm's Law allows you to calculate the amount of current based on the voltage supplied and the resistance of the circuit. I = current V = voltage or potential difference R = resistance I = V/R
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.
The name given by engineers to the ratio of "electrical potential difference" (expressed in volts) to "rate of current flow" (expressed in amperes) is "resistance" (expressed in ohms).
some resistance and potential difference
resistance of a material
You can measure it, but you can't calculate it. That's why the resistance of a resistor is always printed on it, either in numbers or in color bands. Without that marking, the resistor is pretty useless. If it accidentally missed being marked during manufacture, it would be either discarded, or sold surplus for bubkes.
