What would the resistance of the wire if the resistance is 10 ohms be the same if it were twice as long?

The resistance of a conductor is directly proportional to its length, hence increasing the length twice will increase the resistance twice as well. Therefore the resistance will be 2*10 = 20 Ohms

∙ 11y agoFor a circular-section conductor, doubling its diameter will quadruple its cross-sectional area. Since resistance is inversely-proportional to a conductor's cross-sectional area, its resistance would, therefore, fall by a quarter, to 2.5 ohms.

Is ohms bigger unit to megohms?
An ohm is a unit of electrical resistance. A kilohm is 1,000 ohms resistance, while a megohm is 1,000,000 ohms resistance.
What does Resistance 1k8 mean?
I am guessing that what you think is an eight is really the symbol for Ohms which is the Greek Omega. So it would be 1,000 Ohms.
What is resistance expressed in?
Electrical resistance is measured in Ohms.
If 3 resistors of 56 12 and 33 ohms are in parallel what is there combined resistance?
The combined resistance is 7.6049 ohms.
Four 50 ohms are connected in series calculate the current in the circuit?
The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms.

A lenght of cirular wire as a resistance of 1 ohms if its the diameter was double its resistance woul be.?
Its resistance would be half , 0.5 ohms is the answer.
What is the resistance of two extension leads of 95 ohms and 75 ohms when connected together in series?
The resistance across both leads would be cumulative. 95+75= 170 Ohms
What is the value for resistance 1100 ohms?
The number of ohms is, precisely, the value of the resistance.
Is ohms bigger unit to megohms?
An ohm is a unit of electrical resistance. A kilohm is 1,000 ohms resistance, while a megohm is 1,000,000 ohms resistance.
Resistance is measured in what?
Electrical resistance (and impedance) is measured in ohms(Ω).
What is the total resistance is V is 10 volts R1 is 1000 ohms and R2 is 1000 Ohms?
If they're connected in series the total resistance is 2000 ohms. If they're connected in parallel the resistance is 500 ohms.
What is the equivalent resistance of a pair of 8 ohm resistors in series circuit?
Two eight-ohm resistors in series would have a total resistance of 16 ohms. Two eight-ohm resistors in parallel would have a total resistance of four ohms.
Is resistance in a series circuit equal to the largest resistor in the series?
No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!
How much resistance should be on a 5.0 kw heat strip?
Depends on the voltage. Wattage is Volts x Amps. Resistance (ohms) is Volts divided by Amps. So on a 120V circuit, it would draw 41.66 amps. To do that, it would need a resistance of 2.88 ohms. But on a 240V circuit, it would draw 20.83 amps. That would require a resistance of 11.52 ohms. Determine the circuit voltage, then use that to figure the amps, then use that result to calculate the resistance necessary.
What is the Lowest ohms possible?
The lowest resistance is zero ohms.
What are ohms used for?
Ohms are used to measure electric resistance.
What has greater resistance 5ohms or 1000 ohms?
1000 ohms
