    Transmission losses in electricity distribution networks

    Need some help with an electricity query... The formula for power losses in a wire is P_L = I^2 R where I is the current passing through the wire and R is the resistance. If the power transmitted along the cable is P and the voltage level is V, then the losses can be written as P_L =...

    Academic Guidance Studying complexity and networks...?

    I want to study complexity and emergence, but I am not sure what degree I should get. I am a second year college biology student, but I feel like biology lacks the math needed to understand a lot of these concepts. I am now veering towards a math degree, but I have not taken enough math to know...
