What does it mean when a wire is doubled on itself?
wire is doubled on itself means that it has now folded to make its length half and cross section area double.
What happens to current if wire is doubled?
The current is directly proportional to the voltage and inversely proportional to the resistance. So doubling or tripling the resistance will cause the current to be one-half or one-third the original value.
What happens to the resistance of a wire if its area is doubled why?
What happens to resistance when length is doubled? From the equation, we understand that resistance is directly proportional to the length of the conductor and inversely proportional to the crossectional area of the conductor. Doubling the length doubles the resistance.
What will happen to the resistance of a wire whose thickness has been double?
this means when the diameter of the wire is doubled, the resistance will be 1/4 of the original value due to R is inversely proportional to π(d/2)².
What does Ohm’s Law apply to?
Ohm’s law is one of the basic equations used in the analysis of electrical circuits. It applies to both metal conductors and circuit components (resistors) specifically made for this behaviour. Both are ubiquitous in electrical engineering.
Is it possible to double the length of a wire?
No, it is not possible because elastic limit strain is only about 10-3 and wires actually break much before it is stretched to double the length.
Does a light bulb obey Ohm’s law?
An example of this is the filament light bulb, in which the temperature rises as the current is increased. Here, Ohm’s law cannot be applied. If the temperature is kept constant for the filament, using small currents, then the bulb is ohmic.
What happens when a given length of a wire is doubled?
A given length of a wire is doubled on itself and this process is repeated once again. By what factor does the resistance of the wire change? Let the resistance of the wire be R.
What is the purpose of doubling the wire on a screw?
In an electrical context, the wire is frequently doubled on itself to terminate the end of it. It’s just to give more area under the screw in a tunnel type terminal. Write better C++ code with less effort.
Does resistivity change when the wire is doubled on itself?
Under the revised or merged question there are two parts to it. Part one is how does resistivity changes when the wire is doubled on itself. My answer to this question remains unaffected, whether the length of wire is doubled or doubled on itself, resistivity remains unaffected.
How does the length of the wire reduce the resistance?
The length of the wire reduces by 1/2, and the area increases by 2 times. Thus, the resistance of the wire reduced by 1/4 times. Still have questions?
