Choosing the correct combination of a motor and a gearbox for a given application is very important, both in the FIRST Robotics Competition (FRC) and in actual engineering projects. Let's start with three very basic concepts of electricity: namely, electric charge, electric current, and electric circuit. However, for an AC circuit with reactive elements, we have to assess the consumed power differently. Whether we use resistors in DC or AC circuits, they always have the same value of resistance in the system no matter what is the supply frequency. There are two types of current in circuits: alternating current, or AC, and direct current, or DC. In DC circuits, the power of the components is simply the output of the DC voltage times the current in watts. Current is the rate of flow of charge in a circuit, measured in amps.

This chapter covers many basic principles and important concepts that carry a lot of weightage and also importance, considering future studies also. Resistance is a material's tendency to resist the flow of charge (current). In the previous parallel circuit we saw that the total capacitance, C T of the circuit was equal to the sum of all the individual capacitors added together. As a result, one watt will be equal to the volt-ampere result of one-volt times one-ampere (one watt is the rate of consuming energy at one joule per second). An electrical measurement called VARs is used to measure ? When one connects two identical capacitors in , the capacitance will be doubled.
