Web5 de jul. de 2014 · Keep your multimeter handy. For example, it looks like some of your resistors in the picture are marked as follows: red-red-black-orange-brown. If these are 1 percent resistors, the brown band, per the deductive logic, is the 5th, tolerance band. The first three numbers are the three digut value: 220 (red-red-black). WebThe fourth band on a resistor designates its tolerance. The colors used in tolerance band of four-band resistors are as follows: Red = 2%. Gold = 5%. Silver = 10%. The following example shows how the first four bands on a resistor are used to determine the range of possible values for the component.
Resistors are rated according to their maximum power dissipation. Discrete resistors in solid-state electronic systems are typically rated as 1 ⁄ 10, 1 ⁄ 8, or 1 ⁄ 4 watt. They usually absorb much less than a watt of electrical power and require little attention to their power rating. Ver mais A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages Ver mais Two typical schematic diagram symbols are as follows: • ANSI-style: (a) resistor, (b) rheostat (variable resistor), and (c) potentiometer • IEC resistor symbol The notation to state … Ver mais Lead arrangements Through-hole components typically have "leads" (pronounced /liːdz/) leaving the body "axially", that … Ver mais The value of a resistor can be measured with an ohmmeter, which may be one function of a multimeter. Usually, probes on the ends of test leads connect to the resistor. A simple ohmmeter may apply a voltage from a battery across the unknown resistor (with an … Ver mais Ohm's law The behaviour of an ideal resistor is described by Ohm's law: Ohm's law states … Ver mais Practical resistors have a series inductance and a small parallel capacitance; these specifications can be important in high-frequency … Ver mais Adjustable resistors A resistor may have one or more fixed tapping points so that the resistance can be changed by moving the connecting wires to different terminals. Some wirewound power resistors have a tapping point that can slide … Ver mais WebTo understand these letters after the resistance value, you must know the tolerance letter coding for the axial resistors. They include the following: B = 0.1% C = 0.25% D = 0.5% …
