Application problem a piece of wire was cut into 2 pieces in the ratio 7 8 the shorter piece was 14cm find the length of the longer pieces?
If a piece of wire was cut into 2 pieces in the ratio 7:8 and the shorter piece was 14cm, then the length of the longer piece will 16cm.
If a copper wire is 195 cm long what is the length in inches?
76.77"
What is the formula to calculate length of the wire?
There is no formula to calculate the length of a wire. The length of a wire is determined by the distance from the power source to where the load is situated.
If 26 feet 10 inches is cut from a wire that is 44 feet 8 inches long what is the length of wire that is left?
17 feet 10 inches
If 18 feet 10 inches cut from a wire that is 25 feet 8 inches long what is th length of the wire that is left?
6 feet 10 inches
If a slinky is 87 feet of flat wire coiled into 3inch diameter circles how many inches of coiled flat wire were used to make the original slinky What is the answer?
To find the length of coiled wire in the slinky, calculate the circumference of each circle by using the formula 2πr. Then, multiply this by the number of circles (assuming they are all the same size) to get the total length of wire used. Finally, convert the total length to inches if needed.
How Does the length of the wire affect its resistance?
As the length of the wire increases, the resistance also increases. This is because a longer wire offers more opposition to the flow of electrical current compared to a shorter wire. Resistance is directly proportional to length, so doubling the length of the wire will double its resistance.
Will current flow more easily through a long wire or a short wire?
Current will flow more easily through a short wire compared to a long wire because the resistance of a wire increases with its length. A longer wire will have more resistance, resulting in a lower current flow compared to a shorter wire.
Is electric greater in a shorter fat wire or a long thin wire?
Electric resistance is greater in a longer, thinner wire compared to a shorter, fatter wire due to increased collisions between electrons and atoms in the longer wire, leading to higher resistance. This is described by the formula R = ρL/A, where R is resistance, ρ is resistivity of the material, L is length, and A is cross-sectional area.
What happens to the resistance of a filament if it is replaced by a shorter wire?
If a filament is replaced by a shorter wire, the resistance will decrease. Resistance is directly proportional to the length of the wire, so a shorter wire will have lower resistance. This is because there is less material for the electrons to travel through, resulting in less opposition to their flow.
Why a coiled wire does not short the circuit?
I suspect that it is because a coiled wire becomes an electro-magnet which disipates and uses energy, and is therefore not recognized as a short.
A wire that is what would have the greatest electrical resistance?
A long and thin wire made of a material with high resistivity and low conductivity would have the greatest electrical resistance. The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area, so a long, thin wire will have a greater resistance compared to a shorter, thicker wire.
What happens to resistance of the wire if the wire is short?
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
Does long wire have a lower or higher resistance than short wire?
A long piece of wire will have more resistance in it than a shorter one of the same material.
Application problem a piece of wire was cut into 2 pieces in the ratio 7 8 the shorter piece was 14cm find the length of the longer pieces?
If a piece of wire was cut into 2 pieces in the ratio 7:8 and the shorter piece was 14cm, then the length of the longer piece will 16cm.
Does a long wire have smaller resestnce than a short wire?
Not necessarily. Resistance is a function of the material, cross-sectional area, and temperature of the wire, as well as its length. Longer wires typically have higher resistance than shorter wires, assuming all other factors are the same.
What is generated when a permanent magnet is moved in front of a coiled wire and the magnet's magnetic field pushes and pulls electrons in the coiled wire?
an AC, or alternating current
