Title5J20.20 - Inductive vs. Resistive Current Rise
Objective

Demonstrate the difference in time that it takes the current to rise in an inductive circuit vs. a resistive circuit.

StatusAvailable
Assembly Instructions

Instructions
Set up the circuit as shown. You should observe a several second current rise in the inductive circuit as opposed to the much less than one second current rise for a purely resistive circuit which achieves the same ultimate current maximum.
