AC Circuits
The alternating current circuits of this experiment contained resistors and
capacitors.
The goal of these circuit experiments was to measure the effect that the
devices have on the current flow.
This experiment is conducted using a simple
alternating current (AC) circuit containing several resistors and capacitors.
For the AC
circuit with the resistor Ohm’s Law V
R
=I
S
R is used to show the voltage of the AC circuit
can be calculated.
Through several substitutions the equation of V
R
=V
RM
cos ωt is used
to find the voltage across the resistor with respect to time.
For the AC circuit with the
capacitor the equation V
C
=V
CM
cos(ωt +φ) is used to calculate the voltage across the
capacitor with respect to time.
The apparatus for this experiment contains a Pasco CI6512 RLC circuit board
containing a resistor and capacitor.
After the circuit board is set up for the capacitor the
