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 happens to the current when the voltage is doubled and the resistance is constant?
I = E/R If resistance is constant, then current is directly proportional to voltage. Double the voltage ===> the current will also double.
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
Ohm's law applies: Current = Voltage / Resistance As such if you double the resistance of the light bulb you end up with half as much current.
Does resistance increase as the cross-sectional area of the wire?
the resistance can never increase or decrease....... (you can't open the resistor and take out the something and make the resistance increase or decrease)AnswerSince resistance is directly proportional to the length of a conductor, increasing the length of a wire will increase its resistance. For example, if you double its length, you will double its resistance.
How does the length of a wire affect the resistance?
Yes, resistance is directly proportional to the length, and inversely proportional to the cross sectional area. R = p*l/A. Where R is the resistance of the piece of conducting material, p is Greek letter rho, representing the resistivity of the material, l (lower case L) is the length, and A is the area.

The double-stranded structure of a DNA molecule is referred to as the?
The double helix.
What is the value of the resistance when both length and diameter are double?
Doubling the diameter of a circular-section conductor will quadruple its cross-sectional area and, therefore, reduce its resistance by a quarter. Doubling the length of a conductor will double its resistance. So, in this example, the resistance of the conductor will halve.
What are the two reasons for the current to double in a circuit?
Since current = voltage / resistance, I = V/R, the current in a circuit will double if either the voltage doubles, or the resistance is halved.
What happens to the current when the voltage is doubled and the resistance is constant?
I = E/R If resistance is constant, then current is directly proportional to voltage. Double the voltage ===> the current will also double.
If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
What can you say about the sum of two positive integers?
The sum will be a positive integer.It will be at least as large as double the smaller integer and at most as large as double the larger integer.
What happens to the resistance as the area increases?
Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
What do you get when adding double negatives?
A Positive
How can you measure the resistance of field coil?
kelvin double bridge
What is the applications of kelvins double bridge?
to measure unknown resistance
Which is a better conductor between a short wire and long wire?
Double the length is double the resistance. Resistance of a wire is the resistivity of the material, times the length, divided by the cross-section area.
