Resistors Thecoolbritselectronics The resistors often have 4 or 5 colour bands printed on them to show you their value in ohms(Ω) resistors also come in a wide range of power ratings measured in watts(w), for most low powered circuits 1 8 (one eighth) watt 1 4 (quarter watt) 1 2 (half watt) 1w, and 2w are standard. what are know.

Resistor Identification Chart Resistors make it harder for electrons to flow. so, they add resistance to a circuit. resistance is a measurement of how easily electrons can flow through a material, and we measure this in the unit of ohms. many people incorrectly think the resistor acts like a speed bump, slowing the electrons down only momentarily. Resistors are denoted by any label beginning with the letter “r”. this particular circuit board is a computer accessory called a “modem,” which allows digital information transfer over telephone lines. there are at least a dozen resistors (all rated at 1 4 watt power dissipation) that can be seen on this modem’s board. These resistors vary in their construction, power dissipation capacities, and tolerance to various parameters (such as temperature and light). the types of resistors include: carbon composition resistor. thermistor. wire wound resistor. metal film resistor. carbon film resistor. variable resistor. varistor. The resultant resistance for this combination would therefore be: r2 r3 = 8Ω 4Ω = 12Ω. so we can replace both resistor r2 and r3 above with a single resistor of resistance value 12Ω. so our circuit now has a single resistor ra in “parallel” with the resistor r4. using our resistors in parallel equation we can reduce this parallel.

A resistor is a passive two terminal electrical component that limits the current flowing in electrical or electronic circuits. its property to resist the flow of current is called resistance, expressed in ohm (Ω), named after german physicist georg simon ohm. resistors are available in different sizes. Resistors are available with power ratings of 1 8th w (or less for surface mount devices or smd), up to hundreds of watts. the most common are 1 4w (0.25w), 1 2w (0.5w), 1w, 5w and 10w. very few projects require higher powers, and it is often much cheaper to use multiple 10w resistors than a single (say) 50w unit. they will also be very much.
