Concept explainers
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.
Question
Question 1
![1) At tesla Model III electric car runs its electric motors on a 400 Volt circuit and each
individual motor's maximum current consumption is 750 Amps. If the maximum mechanical
output of each motor is 270 kWatt (270,000 watts) what is the efficiency of the motor?
2) Two particles both have a positive charge of 3 coulombs each and present an electrostatic
force between them of 100,000,000,000 Newtons (100 x 10° Newtons), (a) what is the
distance between them in meters? (b) are they repealing or attracting each other?
3) (a) Calculate the resistance of aluminum wire with a cross sectional area of 10 mm2 and
length of 2 meters, the resistivity of Titanium is 0.027 Ohm*mm?/m. (b) If the resistivity of
copper is much lower, 0.0171 Ohm*mm²/m, how long would a wire of copper, with the
same 10 mm2 cross sectional area have to be to have the same resistance as the 2 meter
long aluminum wire?
