So you are agreeing with me; you made exactly the mistake I thought you probably had made. Think about it.JordanHood said:I used I=P/V to get 1x10^9/400x10^3 = 2500A. I then substituted this into Power loss= I^2/R to get 2500^2/5 = 1.25x10^6 W.
ah yes, gosh that was stupid P=i^2*R not divided like I was doingphinds said:So you are agreeing with me; you made exactly the mistake I thought you probably had made. Think about it.
The main cause of power loss in cables is resistance. As the current flows through the cable, it encounters resistance which leads to a voltage drop. This voltage drop results in power loss.
The longer the distance the power has to travel, the higher the power loss will be. This is because the resistance in the cable increases with distance, leading to a higher voltage drop and thus, more power loss.
One way to reduce power loss is to use conductors with lower resistance. This can be achieved by using thicker cables or materials with higher conductivity. Additionally, using transformers at regular intervals along the cable can help to compensate for the power loss.
Temperature can also impact power loss in cables. As the temperature increases, the resistance of the cable also increases, leading to more power loss. It is important to consider the temperature of the environment when designing and installing power cables.
The most immediate consequence of power loss is a decrease in the efficiency of the power transmission. This can result in a decrease in the amount of power reaching the destination and potential disruptions in the power supply. Additionally, power loss can also lead to increased costs and environmental impacts, as more power needs to be generated to compensate for the loss.
