Explanation / Answer

What is the current when the resistance of the photoresistor is 1.6k? ?

Express your answer to two significant figures and include the appropriate units.

current = voltage / total resistance = 9 / ( 1000 + 1600 ) = 0.00346154 A

What is the potential difference across photoresistor when the resistance of the

photoresistor is 1.6k? ?

Express your answer to two significant figures and include the appropriate units.

potential difference = current * resistance of photo resistor = 0.00346154 * 1600 = 5.53846 V
