Question
A three terminal potentiometer with an unconnected terminal is a common rheostat used to vary this quantity. For 10 points each:
[10m] Name this quantity whose value for some components is indicated by four colored bands.
ANSWER: electrical resistance
[10e] Resistance equals voltage divided by current by a law named after this German physicist, who also gives his name to the SI unit of resistance.
ANSWER: Georg Ohm [accept Ohm’s law; accept ohms]
[10h] The strength of an unknown resistor is calculated using one of these circuits. Three resistors of known strength and the unknown resistor are placed in a diamond shape in these circuits.
ANSWER: Wheatstone bridges [prompt on Wheatstone; prompt on bridges; prompt on Wheatstone circuits]
