Question

1.) A 2.00 µF and a 7.50 µF capacitor can be connected in series or parallel, as can a 50.0 kΩ and a 100 kΩ resistor. Calculate the four RC time constants (in s) possible from connecting the resulting capacitance and resistance in series.

resistors and capacitors in series: __________s

resistors in series, capacitors in parallel: ____________s

resistors in parallel, capacitors in series:________________s

capacitors and resistors in parallel: ____________________s

2) A 1.16 MΩ voltmeter is placed in parallel with a 75.5 kΩ resistor in a circuit.

a)Draw a circuit diagram of the connection

b) What is the resistance of the combination? (Enter your answer in ohms to at least 3 significant figures.): ________ Ω

c) If the voltage across the combination is kept the same as it was across the 75.5 kΩ resistor alone, what is the percent increase in current?: ________%

d)If the current through the combination is kept the same as it was through the 75.5 kΩ resistor alone, what is the percentage decrease in voltage?_______%

e)
