Week-6 Challenge: EV Drivetrain

heat generated = joules heat + entropy heat joules heat from ohms law we know that  V=IR when the current flowing through a resistance, there is a heat dissipated inn the resistor this  heat dissipation is called joules heating. joules heating is also known as ohmic heating power P=V*I=I^2*R heat H=∫P.dt…
