Problem 1
Determine the time constant of the RC circuit shown in the figure below. Is this
circuit set up for charging or discharging? - ANSWER: RC Circuits
Problem 2 If the capacitor in the RC circuit shown in Problem 1 was initially charged
to 35 µC, determine the time it takes for the capacitor to have only 1 µC of charge
remaining on it. - ANSWER: RC Circuits
Problem 3 Consider the RC circuit shown below. The switch is initially in position A,
and has been for a very long time. Determine the charge on the capacitor. -
ANSWER: RC Circuits
Problem 4 The switch in Problem 3 is suddenly thrown over to position B. Determine
the length of time required for the capacitor to discharge 50% of its original charge. -
ANSWER: RC Circuits
Problem 5 An unknown resistor and capacitor are connected in series to a battery as
shown in the figure below. At time t = 0 s, the switch is closed. After 0.5 µs, the
current is measured to be 1% of its original value. Determine the time constant of
this system. - ANSWER: RC Circuits
Problem 6 A 100 Ω resistor and unknown capacitor are connected in series to a
battery as shown in the figure below. At time t = 0 s, the switch is closed. After 0.5
µs, the voltage across the capacitor is measured to be 15% of its maximum value.
Determine the capacitance of the capacitor - ANSWER: RC Circuits
Problem 7 With the switch closed, find the reading of the ammeter. Which direction
does the current flow through the switch (up or down)? - ANSWER: RC Circuits
