A 12-volt battery is connected to two light bulbs, as drawn in
Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2
has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,
too.
When a light bulb is unscrewed, no current flows through that
branch of the circuit. For instance, if light bulb 2 is unscrewed,
current flows only around the lower loop of the circuit, which
consists of...

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....
