Remarques
E24 series resistors have a standard tolerance of 5%. Each decade contains 24 values with a ratio of approximately 10^(1/24) = 1.101 between adjacent values.
Calculateurs Associés
Color Code
Decode resistor color bands to resistance value and tolerance. Supports 4-band and 5-band resistors; the 6th (temperature-coefficient) band of a 6-band resistor is not decoded. Instant color band to ohms conversion.
Voltage Divider
Calculate voltage divider output voltage, current, Thévenin impedance, and power dissipation from Vin, R1, and R2. Ideal for bias networks and level shifting.
LED Resistor
Calculate the correct current limiting resistor for an LED. Shows exact value, nearest E24 standard, actual current, and power dissipation.
Series/Parallel R·C·L
Calculate the equivalent series and parallel combination of up to four resistors, capacitors, or inductors. Also computes the voltage divider ratio for two-resistor networks.
