Why is the energy loss in electricity generation much higher than the energy loss in transmission and distribution?
OA
because electric generators operate at a low voltage
OB.
because of the higher voltage in the transmission and distribution lines
Ос.
because of the low efficiency of current electric generators
OD
because of the high resistance of transmission and distribution wires
