Ceramic Resistor Schematic Symbol

Resistor values in ohms are usually shown as an adjacent number and if several resistors are present in a circuit they will be labeled with a unique identifier number such as r 1 r 2 r 3 etc.

Ceramic resistor schematic symbol. The resistors are passive components manufactured specifically to provide a given value of resistance to the passage of electric current. A thermistor is a type of resistor whose resistance is dependent on temperature more so than in standard resistors the word is a combination of thermal and resistor thermistors are widely used as inrush current limiters temperature sensors negative temperature coefficient or ntc type typically self resetting overcurrent protectors and self regulating heating elements positive. Resistor schematic symbols and values the most common schematic symbol for a resistor is a zig zag line. A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element.

The first two symbols are used in uk while the next two symbols in us. The have positive and negative terminals and the top of these symbols represent the positive terminals. The 5 th symbol for capacitor is used in japan. Battery semiconductor devices etc.

Basically electronic components are classified into active components and passive components. In electronic circuits resistors are used to reduce current flow adjust signal levels to divide voltages bias active elements and terminate transmission lines among other uses high power resistors that can dissipate many watts of electrical power as heat may be used as. The components that supply the energy to the circuit are called as active components.
