With the switch in the circuit of Figure a open, there is no current in R2. There is current in R1, however, and it is measured with the ammeter at the right side of the circuit. If the switch is closed (Figure b), there is current in R2. What happens to the reading on the ammeter when the switch is closed? a) The reading increases; b) The reading decreases; c) The reading does not change.

The convention for voltmeters is to use a black wire for the negative reference terminal and a red wire for the positive reference terminal. Explain why two wires are required to measure a voltage. If the wires into the voltmeter are swapped by accident, what will happen during the next measurement?
