A) there is less heating in the transmission wiresB) the resistance of the wires is less at high voltagesC) more current is transmitted at high voltagesD) the insulation is more effective at high voltagesE) the iR drop along the wires is greater at high voltageHow does the voltage of the line affect the final power output? Thanks.
I stay in long island, and that i went right into a gun save and attempted to purchase an airsoft gunthe guy stated I had to be sixteen to purchase one, and 18 for bb or pellet weaponsyou need to use an airsoft gun at any age, nonetheless, even a three 365 days previous can shoot one.
Why is it better to send 10,000 kW of electric power long distances at 10,000 V rather than at 220 V? There are 2 equations for Power Eq1…Power volts amps Eq2.Power amps^2 resistance Using Eq1 If the volts 10,000 v 10,000 kw 10,000 v I I 1 amp, the current is lowIf the volts 220 v 10,000 Kw 220 v I I 45.45 amps, the amps is high The transmission wires have a specific resistanceLet r resistance of transmission wires As the current flows through the transmission wires the resistance causes the wires to get hotThis heat energy is emitted into the insulation on the wire and into the airThis means less electric energy for the customersEq2.Power amps^2 resistance At 10,000 v, only 1 amp is flowing through the transmission wire, so the energy loss due to heat 1^2 r Joules 1 r Joules At 220 v, 45.45 amps is flowing through the transmission wire, so the energy loss due to heat 45.45^2 r 2066 r Joules Also, as the wire gets hotter the resistance increasesSo more heat is producedA) there is less heating in the transmission wires YES B) the resistance of the wires is less at high voltages C) more current is transmitted at high voltages D) the insulation is more effective at high voltages E) the iR drop along the wires is greater at high voltage
