1.1.4 Component Identification-AnalogResistors
➢ electronic component that resists the flow of electrical current➢ typically used to control the amount of current that is flowing in a circuit➢ measured in Ohms (Ω)
○ named after George Ohms, whose law (Ohm’s Law) defines the relationship between voltage, current, and resistance
Resistor Types
Determining a Resistor’s Value➢ Color Code
○ resistors are labeled with color bands that specify the resistor’s nominal (face) value
➢ Measured Value○ digital multimeter can be used to measure the resistor’s actual resistance value
How to Read a Resistor’s Value
Capacitors➢ electronic component that can be used to store an electric charge➢ often used in electronic circuits as temporary energy-storage devices➢ capacitance is measured in units of farads (F)
○ named after Michael Faraday (British chemist who contributed significantly to the study of electromagnetism)
Capacitor Types
How to Read a Capacitor’s Value➢ Electrolytic Capacitors
○ directly labeled on capacitor➢
➢ Disk Capacitors
○ Note: units on disc capacitors are always in pico-farads
