To limit the amount of current to the ports
Slip rings are needed to connect a rotating armature to external fixed circuits.
R = E/I = (12)/(0.1) = 120 ohms(Make it a big one. It dissipates I2R = 0.01 x 120 = 1.2 watts.)
The things needed to build a circuit are:Circuit elements like resistor capacitors, inductors etcConnectors (cables)A source
The resistor bypass in the ignition circuit is used when starting the engine. It bypasses the resistor to provide full battery voltage to the ignition coil, ensuring a strong spark for a quick and reliable engine start. Once the engine is running, the bypass is no longer needed and the resistor is re-engaged to limit the voltage to the ignition coil for normal operation.
You will need to take the resistance of the load into account if you are going to design a voltage divider. The resistance of the load can completely change the voltage ratio of a voltage divider if not factored into the calculation. you can measure or read R(load), then R(needed) = 0.8 R(load)

you better not. you need a 9V regulator for this, not a resistor!
There should be some process to stop the execution of a program.In microcontroller it is done by jumping to same location.

A fuel pump resistor runs the fuel pump at a lower speed when the demand for fuel is lower. When more fuel is needed the system bypasses the resistor and allows the fuel pump to run at full speed.
Yes. You probably don't want to do so directly unless it's a really small motor. An H-bridge, or similar circuit is probably easiest to use. The microcrontroller would interface with the computer, likely through a serial link. The microcontroller would then control the H bridge through several outputs. Depending on the microcontroller, H-bridge design, and motor to be controlled, the microcontroller might not be able to drive the H-bridge and an intermediate driver chip may be needed.
You actually have that reversed. A microcontroller is connected to a relay via a ULN2803 (or other power device driver IC) because the output pins of the microcontroller can't drive relays. The ULN2803 darlington transistors provide the power amplification and the inductive kickback protection needed to drive the relay while only lightly loading the microprocessor output pins.

The amount of external financing needed for the project to be successfully completed is the total funding required from sources outside of the project itself.
It doesn't work that way. An oxygen sensor can not be bypassed.
Its dependent what will by rated power of the device (current).
A zero-ohm resistor does not exist, so we are talking about an ideal resistor. An ideal resistor is needed for description in a circuit, where we lump all wire/parasitic resistances into discrete resistors, but the wire joining two discrete resistors is considered to have no resistance. My definition: a zero-ohm resistor is an ideal resistor that does not consume energy when a current exists in the resistor. Alternatively, a zero-ohm resistor is an ideal resistor that cannot sustain any potential drop when a current is on. Thirdly, a zero-ohm resistor is an ideal resistor that will conduct an infinite current when a voltage is applied across it.
