Kirchhoff's Voltage Law
Investigate Kirchhoff's voltage law.
Part of the course: Electricity & Circuits I — DC Fundamentals
Mission
Investigate Kirchhoff's voltage law
Variables
What you change
- Resistance value
What you measure
- Voltage Drop
What you keep constant
- Wire length
- Wire cross section
- Battery voltage value
- Temperature of wire
Equations
V_1 = Voltage drop on first resistor (V)
V_2 = Voltage drop on second resistor (V)
V_3 = Voltage drop on third resistor (V)
V_4 = Voltage drop on fourth resistor (V)
V_5 = Voltage drop on fifth resistor (V)
V_Bat ≈ 6 Volts
R_1, R_2, R_3, R_4, R_5 = Resistors (ohm)
V_Bat = V_1 + V_5
V_Bat = V_2 + V_3
V_Bat = V_2 + V_4 + V_5
What You'll Need
- Breadboard 400 Tie Point
- Arduino Uno
- I2C LCD
- 25V Voltage Sensor Module
- 6V Battery Pack, 4x AA
- Resistor
