Resistors Resistors An electrical component that opposes the flow of electrons - - ?...! - - - - - - - - - - - Resistors reduce the electrical pressure Voltage is dropped Current remains the same - - - - - - - - - - - - - - - - - So there is an energy change! Then what’s all this energy being converted into? - - - - HEAT - - - - - - - - - - - - - - - - Types of Resistors Fixed - resistor Variable -potentiometer Light sensitive -photoresistor Thermal- thermistor The Resistor Code Decoding Resistor Values Reading the Resistor Start at band closest to the end of the resistor 1st Digit 2nd Digit # of Zeros Tolerance Stripe Tolerance Stripe The tolerance is the amount in percent that the resistor is allowed to be off from its stated value +/-20% -No Stripe +/-10% -Silver Stripe +/-5% - Gold Stripe What is the value of this resistor? Tolerance Band 4 7 00 10% = 4.7KΩ +/- 10% What’s this thing? ` Omega- a Greek symbol used to represent Ohms, the unit of measure for resistance!
