C array declaration. Arrays can be declared in various ways in different languages. For illustration, let's take C array declaration. As per the above illustration, following are the important points to be considered. Index starts with 0. Array length is 10 which means it can store 10 elements. Each element can be accessed via its index. For ...

If we neglect the rotational losses, the motor must produce force Fm opposite to Fl to move the bus in the uphill direction. Here the motor is still in the same direction on both sides of the hill. This is known as regenerative braking. The energy is exchange under regenerative braking operation is power flows from mechanical load to source.
