Light emitting diodes (LEDs) (2) - 330 Ohm resistors (orange/orange/brown/gold or silver) Digital multimeter (DMM) #22 Gauge solid wire Procedure Follow the instructions to create different types of circuits. As you create each circuit‚ you will be asked to make measurements and record observations to gain understanding about the circuit and its components. Let us begin by investigating two components that are commonly used in circuits. They are resistors and Light Emitting Diodes (LEDs). Part A:
Premium Resistor Series and parallel circuits Electrical resistance
components: Series parallel 1. Series Circuit – is an electric circuit having its parts connected serially (without branching). It has only one path for the charges to move along and the charges must move in “Series” which means first going to one resistor then the next. Here if one of the circuits is broken down‚ then no charge will move through the circuit because there is only one path. Which is if one bulb burned out the whole lights will go off. The lamps on a Christmas tree are connected in series

inside that allows power to run through. Power then runs to various capacitors to store up power before running to the inductor that converts the power to usable power for the MOSFETs. As the power runs through the circuit‚ it eventually comes to resistors which slow up the current flow. Sound comes in through the inputs and to the MOSFET amplifiers. Then sound goes to the sound dampeners to clean the sound waves up before going to the sound outputs. To better understand the amp and its components
Premium Electric current Resistor Ohm's law
positive leg is about 1.4 volts higher than the voltage on the negative side. Remember that there is no resistance to limit the current so a resistor must be used in series with the LED to avoid destroying it. Resistors Resistors are components that have a predetermined resistance. Resistance determines how much current will flow through a component. Resistors are used to control voltages and currents. A very high resistance allows very little current to flow. Air has very high resistance. Current
