Resistors in series

“

- [Instructor] Analyzing a circuit with a single resistor is easy. Ohm's law makes the relationship between the voltage, current and resistance of that resistor very straightforward. Things start to get a bit trickier, though, when we combine multiple resistors and other components together in complex arrangements. The simplest way that resistors can be connected to each other is in series. Resistors connected in series are attached to each other end to end. In this arrangement, the combined total resistance of the series of resistors is equal to the sum of all of their individual resistances. We can treat this collection of resistors in series, as a single resistor with a larger resistance value. One reason for combining multiple resistors in series, is to create a resistor value that you could not otherwise have available. For example, if I needed a 3 kilo ohm resistor for my circuit, but all I had in my box of parts…
