burden resistor     It is a regular resistor. The name refers to the function,
                    not to the resistor's construction. Current transformers 
                    act as current sources and need a load. A current source 
                    is the dual of a voltage source, and just like you 
                    shouldn't short-circuit a voltage source because it would 
                    cause infinite current, you shouldn't leave a current 
                    source open, as it would cause an infinite voltage. The 
                    `burden resistor <https://electronics.stackexchange.com/questions/36341/what-is-the-difference-between-burden-resistor-and-a-normal-one>`_
                    converts the current to a limited voltage.
