• We introduce an inverse engineering approach to drive an RC circuit. This technique is implemented experimentally (1) to reach a stationary regime associated with a sinusoidal driving voltage in a very short amount of time, (2) to ensure a fast discharge of the capacitor, and (3) to guarantee a fast change from one stationary regime to another driven at different frequencies. This work can be used as a simple experimental project dedicated to the computer control of a voltage source. Besides the specific example addressed here, the proposed method provides an original use of simple linear differential equations to control the dynamical quantities of a physical system and has therefore a certain pedagogical value.
