A student mistakenly connects a real voltmeter in series with a light-bulb and a battery instead of placing the voltmeter across the bulb. Which statement best describes the bulb’s brightness in this incorrect setup compared to when the voltmeter is connected correctly?
(a) The bulb is brighter, because the voltmeter increases the voltage across the bulb.
(b) The bulb is considerably dimmer, because the voltmeter’s large resistance greatly reduces the circuit current.
(c) The bulb’s brightness is unchanged, because the voltmeter’s high resistance means it never affects a circuit.
(d) The bulb does not light at all, because the voltmeter’s very large resistance effectively breaks the circuit.
