Fert Berfel is a very naive individual who sets out to takecurrent readings with an ammeter as one would take voltagereadings: by simply touching the probes to two locations. Thecircuit involved is very simple. A red wire goes from the +terminal of a battery to one terminal of a light bulb. A black wiregoes from the other terminal of the bulb back to the – terminal ofthe battery. First he touches the probes to opposite ends of thered wire. What reading does he get? Now he touches the twoterminals of the bulb. What reading does he get? Assuming he nowgoes and buys a new ammeter to replace the one he destroyed, howshould he read the current in the red wire?
