Question

The time constant of a resistive/capacitive circuit is defined as:

		The product tC (time x capacitance)
		Time divided by RC (time/(resistance x capacitance))
		The product VI (voltage x current)
		The product RC (resistance x capacitance)

The function generator will be used to generate a square wave which will:

		Create a force on the resistor
		Charge and discharge the capacitor through the resistor
		Allow a graph to be produced on the computer
		Be converted to a sine wave through inductance

There are two statistical analysis requirements in this experiment. They are:

		Calculate % difference and relative uncertainty of the function generator
		Calculate the resistor and capacitor tolerance
		Compare the calculated tolerances of the resistor and capacitor and compare to the % difference, and calculate the % uncertainty due to scope measurement error
		Calculate the standard deviation of the scope timescale and the voltage probe readings

A small time constant of an RC circuit means

		the resistor will store more charge than the capacitor
		the capacitor will discharge slow
		the capacitor will discharge fast
		none of the above

Answer 1

1.

The time constant of a resistive/capacitive circuit is defined as: The product RC (resistance x capacitance).

The formula for time constant , tau = R*C

2 .

The function generator will be used to generate a square wave which will: Charge and discharge the capacitor through the resistor.
