Abstract | Presents activities to determine whether it is better to test dry cells with an ammeter than with a voltmeter and how best to test alkaline batteries. Discusses classification of disposable testers as instruments. Concludes that a laboratory voltmeter gives a good indication of the condition of an alkaline cell while carbon batteries are best tested with an ammeter. (JRH) |
