Resistors ... line loss |

Resistance = V/I measured in OHMs
> the resistance of
a resistor changes as it heats up or cools > typically the resistance of a resistor increases as temperature increases Line loss .... is the power lost when
power is transmitted
over a distance because even conductors have
resistance that accumulates over distance example:100 ft length of # 14AWG copper conductor has about 2.575 ohms What power would be lost if 15A is sent over 11000 feet (about 2 miles/3.2Km) ? |
