Quantitative Behavior of RC Circuit
Task: You will be filling in the data table below with 10 rows of data that will track the time elapsed (the ‘Charging Time’), the voltage across the resistor, the voltage across the capacitor, the charge of the capacitor, and the current in the circuit.
Example table:
Elapsed time (s) |
Voltage across resistor (V) |
Voltage across capacitor (V) |
Charge on capacitor (µC) |
Current in circuit (mA) |
I only need clarification on these few questions:
It means You have to convert mA to A (i.e by multiplying with 10-3 ) and draw a graph with Voltage across resistor (V) on Y axis and Current on X- axis , like shown below
The Slope of the trend line will be the value of resistor you have used in the circuit.
Theory : The slope of V-I graph gives the resisance of the circuit.
By Ohms law, Resistance,
The Slope of the trend line will be the value of capacitor (in C) you have used in the circuit.
Theory : we know that charge stored on your capacitor, Q = CV
then, the slope of trend line =
