Kenny's father bought him two cables that he can use for his project: a 200 cm cable, and a 50 cm cable. Kenny wants as little resistance in his circuit as possible. If both cables are made with the same conductor material, then which cable should he use?
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
Kenny's father bought him two cables that he can use for his project: a 200 cm cable, and a 50 cm cable. Kenny wants as little resistance in his circuit as possible. If both cables are made with the same conductor material, then which cable should he use?
A. The 200 cm cable, because the longer a circuit is, the less resistance it has
B. The 50 cm cable, because the longer a circuit is, the more resistance it has
C. Either the 50 cm cable or the 200 cm cable, because they have the same resistance
D. Neither the 50 cm cable nor the 200 cm cable, because both of them have a resistance
