A 120. - V motor has mechanical power output of 2.50 hp. It is90.0% efficient in converting power that it takes in by electricaltransmission into mechanical power. (a) Find the current in themotor. (b) Find the energy delivered to the motor by electricaltransmission in 3.00 h of operation. (c) If the electric companycharges $0.110/kWh, what does it cost to run the motor for3.00 h?
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.
