How To Read Ceramic Resistor Value

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

How to read ceramic resistor value.

When the first two numbers are multiplied with the multiplier the. Resistors never start with a metallic band on the left. In formula form v ir where v is the voltage across the resistor r is the value of the resistor in ohms and i is the current flow through the resistor in amperes amps. Then jot down the sequence of the colored bands reading from left to right.

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. Electrical resistance in serial and parallel networks resistors in parallel and serial connections. Next check the voltage rating which is usually listed as a number followed by the letters v vdc vdcw or wv. Position the resistor with this band on the right side and again read your resistor from left to right.

To read an axial lead resistor hold the resistor so the gold or silver band is facing to the right. Method of finding the value meaning of codes of capacitor. Basic resistor values range from 0 1 ohm to 10 megaohms. There are two main types of resistors.

Standard resistors have four color bands. Then look for a tolerance value typically listed as a percentage. The manufacturing process isn t perfect so most resistors are a little off. Always wondered why they called them wire wound resistors.

Method of finding the value of the through hole resistor digit digit multiplier tolerance for 4 band resistor digit digit digit multiplier tolerance for 5 band resistor yellow violet red 4 7 2 4 7 x 102 4700ω or 4 7or 4k7. If you have a resistor with a gold or silver band on one end you have a 5 or 10 tolerance resistor. Parallel circuits resistance voltage and current in parallel networks. How to read color code of resistor must read what is 555 timer.

To read a large capacitor first find the capacitance value which will be a number or a number range most commonly followed by µf m or fd. Electrical electrical units amps and electrical wiring wire gauge and awg electrical formulas and motors. Make sure to read the value of the right most color band to determine the tolerance of the resistor. Resistors color codes calculator color codes for fixed resistors.

Three of the bands tell you the nominal value which means the value the resistor was designed to have the fourth band tells you the tolerance of the resistor which indicates how far off the nominal value the actual resistance could be. Easy to open them up with a hammer and what you have is some kind of wire alloy.
