WileyPlus Homework 1

Homework 1 has been posted to WileyPlus. One of the problems involves a circuit like this one:


The (ideal) voltmeter is equivalent to an open circuit. In particular, the voltage across the open circuit is equal to the voltage measured by the voltmeter. The color coded voltmeter probes indicate the polarity of the open circuit voltage.

Here's a similar circuit.

The (ideal) ammeter is equivalent to a short circuit. In particular, the current in the short circuit is equal to the current measured by the ammeter. The color coded ammeter probes indicate the reference direction of the short circuit current.

Typical questions ask for the value of the resistance or the power supplied by one of the sources. Answering such questions requires that we pay attention to the "passive convention".
