Principles Of Engineering. What is a Breadboard?. Sometimes called a proto-board. Reusable platform for temporarily built electronic circuits. Why Breadboard?. It takes less time (and money) to breadboard a circuit than to design and fabricate a printed circuit board (PCB. Resistance. Voltage. Current is a function of these two. What if we want to control the current or alter the voltage?. Change the Resistance!. How do we do this?. Which of the three parts of Ohm’s triangle do we have the most control over?. resistors. A resistor, like batteries and lights, can also be present in an electrical circuit. A resistor limits the flow of electricity in the circuit. Like rocks in a pipe that slow the flow of water, a resistor will limit the flow of electricity. A variable resistor is made of a piece of metal that can change in length. As the length of the resistor changes, so does the resistance in the same direction. . Outline. Resistors in series. Resistors in parallel. The voltage divider and the current divider circuits.
