An unmarked box is found in the back corner of a laboratory. It has two wires protuding from it, an orange wire and a purple wire. A voltmeter is connected to the two wires with the + reference on thepurple wire. A voltage of -2.86V is measured in this fashion. What would the voltage reading be if the voltmeter connections were reversed.
