Current Sources in Superposition Theorem

JSGandora · Mar 11, 2011

Why do we replace current sources with open circuits when using the Superposition Theorem while we replace batteries with wire?

Because you're supposed to substitute each source with a source of value 0. A shortcircuit (cable) is a battery (voltage source) with an EMF of 0 V. An open circuit is a current source with 0 A; remember that in an open circuit no current can flow, but the voltage drop could be anything. In a current source of 0 A, no current can flow, but the voltage drop could be anything.
