As fluid flows through a pipe, frictional drag forces at the walls dissipate energy from the flow and thus reducing the pressure, or equivalently, the potential energy of the fluid in the pipe. A small resistor is equivalent to a large diameter pipe that will allow for a high flow rate, whereas a large resistor is equivalent to a small diameter pipe that greatly constricts the flow rate.

Many teams will tie-wrap these two wires together, which is a very bad idea. The pulse from the coil wire is very strong and interferes with the ignition signal.

When this happens, see if there is a short circuit or a disconnection, then install a new fuse of the correct amperage rating.

If your terminal is attached by a nut to a post, use lock washers and if it is a very important connection, and most are, use blue Loctite on the post. Many electrical failures are random and due to loose connections that are hard to trace. A quick look and the connection looks good, but if it is loose, it will cause an interruption of the current flow periodically.

This type of circuit is called an earth-return system any part of it connected to the car body is said to be earthed. If the battery voltage drops, less current flows, and eventually there is not enough to make the components work.

The output voltage is controlled using a feedback loop, which requires some type of compensation to assure loop stability. Most linear regulators have built-in compensation, and are completely stable without external components. Some regulators (like Low-Dropout types), do require some external capacitance connected from the output lead to ground to assure regulator stability.

If more than one drive is being operated from the power supply this is not a problem since the other drive(s) will absorb this current for its needs, unless it is decelerating as well. For this case or for a single drive it may be necessary to place a voltage clamp across the power supply in the form of a Zener diode. The voltage of this diode must be greater than the maximum expected power supply voltage, yet low enough to protect the drive. A good choice would be either 82 volts or 91 volts as standard values.

For dynamic signals, the transfer function cannot in general be described simply. However, if the input is a sinusoidal signal then the output must also be a sinusoidal signal with the same frequency but possibly a different amplitude and phase. In other words, a linear system can only modify the amplitude and phase of a sinusoidal input.
