What the Experiments Cover
Current and conductors: electric current, solid conductors tested with the material samples, and liquid conductors. Switching: AND/OR and two-way circuits, relays and bells, and two lamps. Sources: voltaic cells, connecting voltage sources and the internal resistance of a battery. Resistance: V-I characteristics, determining a resistance, and resistors in series, in parallel and in combination. Meters and power: practice in reading an analog multimeter, and electrical power in circuits.
A Cell in the Beaker and a Battery Under Load
Held by the electrode cover in the beaker of 2% sulfuric acid, the zinc and copper plates form a simple voltaic cell whose voltage the multimeter reads, with zinc as the negative plate; the acid calls for eye protection. In the internal-resistance experiment, drawing current through a resistor makes the battery’s terminal voltage fall below its open-circuit value, and the drop divided by the current gives the internal resistance, from V = E − Ir. The plug-in resistors also show that resistances add in series, while a parallel pair gives less than the smaller one.
