Method: Joules.capacitance_in_series

Defined in:
lib/joules/electricity.rb

.capacitance_in_series(capacitances) ⇒ Float

Calculates the total capacitance of capacitors in series.

Examples:

Joules.capacitance_in_series([0.5, 0.25, 0.125]) #=> 0.07142857142857142

Parameters:

  • capacitances (Array<Int, Float>) —

    each capacitance in resistances != 0; each capacitance in capacitances is in farads

Returns:

  • (Float) —

    return value is in farads
