A student assembles a circuit. The circuit diagram shows the way the positive terminal and negative terminal of a voltmeter are joined to the circuit. The voltmeter gives an initial positive reading. Which changes, if any, in temperature and light intensity would make the voltmeter reading fall?
- Atemperature increase, light intensity increase
- Btemperature no change, light intensity decrease
- Ctemperature decrease, light intensity no change
- Dtemperature decrease, light intensity decrease
