The calculator to find the closest standard capacitor (or resistor) value in each of the IEA series. E192: 0.5%, 0.25%, 0.1% resistors E48: 2% resistors. E24: 5% resistors. E12: some capacitors, 10% resistors. E6: most capacitors, some inductors. Thinkcalculator.com provides you helpful and handy calculator resources.The different sets of standard resistor values are known by their E-series numbers: E6 has six resistance values in each decimal interval, E12 has twelve, E24 has twenty-four and so forth. Table of all nominal resistance values of resistors, which conform to E24 series. Е24 1.0 1.1 1.2 1.3 1.5 1.6 1.8 2.0 2.2 2.4 2.7 3.0 3.3 3.6 3.9Orange, black, black, brown, brown--> 3.00 k ohms, 1% - note: this is a non-standard 1% (E96) resistor, but some manufacturers make every value from the E24 series with 1% tolerance!

(b) Step 1: The resistors R3 and R4 are in series and the equivalent resistance is R34 = 10Ω (c) Step 2: The reduced circuit shows resistors R2 and R34 are in parallel, with an equivalent resistance of R234 = 5Ω.
The other series within the range of the E-series are the E12 and E24 series whose values are calculated at the interval of every ten years and consists of twelve and twenty-four values for a tolerance level of ±10% and ±5% respectively.
I'm trying to build a dc motor controller circuit as described here. But it requires 2 "150E" resistors From looking online I believe this means 15 ohms but I'm curious as to why, and why I couldThe values of resistors are of course quoted in Ohms (Ω), though with high values, Kilohms (KΩ) or Megohms (MΩ) are common units. With low values a circuit diagram may state a resistance value as for example 15R instead of 15Ω.
The ordering code of a VRC01 resistor, value 1 MΩ with ±5% tolerance, supplied in tape of 5,000 units per reel is: 232279061105L or RV1206JR-071ML. Including values 10/11/13/15/20/75 of E24 series First two digits for E-96 marking rule and 3rd letter for number of zeros RV0805/1206/2010/2512 Both E-24 and E-96 series: 4 digits, ±0.5%
