Voltage Calculator is a fast, focused toolbox for everyday electronics work. Three calculators in one clean, dark interface give you instant answers while you type.
KEY FEATURES
• Series & parallel calculator: combine up to 15 resistors or capacitors and read the result in every common unit
• LED series resistor: enter supply voltage, forward voltage and forward current to get the right resistor and its power rating
• Built-in reference table of typical LED forward voltages
• Voltage divider: calculate the output voltage, or find the missing resistor for a target output
• Live circuit diagrams that show your values in place
• Results update instantly in multiple units as you type
• Available in 24 languages
