In electronics, especially audio and sound recording, a high impedance bridging, voltage bridging, or simply bridging connection is one in which the load impedance is much larger than the source impedance. In cases where only the load impedance can be varied, maximizing the load impedance serves to minimize the current drawn by the load, and maximize the voltage signal across the load. Essentially, the load is measuring the source's voltage without affecting it. In cases where only the source impedance can be varied, minimizing the source impedance will maximize the power (and the current) delivered to the load and, as before, maximize the voltage signal across the load.
