In a complex circuit with various elements (resistors, capacitors etc.) and one battery, the various circut elements contribute to draw a certain amount of current "I"from the battery at some terminal voltage "V". The "equivalent" resistance of the various circuit elements is that resistance "R" which will draw the same current , at the same terminal voltage, as the complex circuit. So to find "R" you simply imagine replacing the complex circuit with "R" by attaching "R" across the terminals of the battery and use Ohms law to find "R" , demanding "I" and "V" are the same. So then R = V/I.
Potential Difference (V) across two resistors is directly proportional to the resistance (R) as greater the potential difference, greater is the resistance and vice versa.
i think its resistance
resistance of a material
The answer will depend on what information is plotted on the graph!
That's Ohm's law. Volts = Current (or Amps) * Resistance.http://en.wikipedia.org/wiki/Ohms_law
I don't no
Potential Difference (V) across two resistors is directly proportional to the resistance (R) as greater the potential difference, greater is the resistance and vice versa.
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
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
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Resistance (Ohms) = Potential Difference (Voltage) / Current (Amps)
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance
i think its resistance
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.
That is the resistance, measured in ohms.
