Assuming 95.0% efficiency for the conversion of electrical power by the motor, what current must the 12.0-V batteries of a 833-kg electric car be able to supply to do the following? (a) accelerate from rest to 25.0 m/s in 1.00 min (A) (b) climb a 200-m high hill in 2.00 min at a constant 25.0 m/s speed while exerting 383 N of force to overcome air resistance and friction (A)
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.
