The copper windings of a motor have a resistance of 50 ohm at 20°C when the motor is idle. After the motor has run for several hours, the resistance rises to 58 .What is the temperature of the windings now? Ignore changes in the dimensions of the windings.
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 copper windings of a motor have a resistance of 50 ohm at
20°C when the motor is idle. After the motor has run for several
hours, the resistance rises to 58 .What is the temperature of the
windings now? Ignore changes in the dimensions of the windings.
