A light bulb and a resistor are connected in series to a variable power supply. A student first connects a voltmeter and an ammeter to measure the current through and the voltage across the bulb, as shown in the left circuit below. The student varies the power supply voltage and records the readings on the meters. Power Supply Power Supply The student then places the voltmeter across the resistor as shown in the right circuit above, and repeats the experiment....
