The current in a certain wire at 20.0°C is 2.40 A when thepotential difference between the ends of the wire is 1.50 V. If the wireis heated to 80.0°C and the potential difference remains the same, thecurrent decreases to 2.00 A. What is the resistance of the wire at 20.0°C? At 80.0°C?
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.
The current in a certain wire at 20.0°C is 2.40 A when the
potential difference between the ends of the wire is 1.50 V. If the wire
is heated to 80.0°C and the potential difference remains the same, the
current decreases to 2.00 A. What is the resistance of the wire at
20.0°C? At 80.0°C?
