Answer:
Heat can be transferred in 3 ways.
Explanation:
Conduction- The process of transmission of heat in solids,without the actual movement of particles.
Convection- A process of transmission of heat in fluids (liquids and gases)with the actual movement of particles.
Radiation- It is the process of transmission of heat without any medium.
Answer:
It is given that power = 5000 W for 120 V and resistance is per 1000 ft of wire. The wire is 750 ft away from 120 V source. We need find the voltage delivered to this load.
Resistance of 750 ft wire, =
Using Ohm's Law:
Voltage delivered to the load,
