Voltage in Resistors Connected in Series
How total voltage is distributed among components.
Part of the course: Electricity & Circuits I — DC Fundamentals
Mission
Studying how the total voltage of the circuit is distributed among the components of the circuit
Variables
What you change
- Resistance value
What you measure
- Voltage Drop
What you keep constant
- Wire length
- Wire cross section
- The voltage of the power source
- 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_Bat ≈ 6 Volts
R_1, R_2, R_3 = Resistors (ohm)
V_1 = \frac{V_Bat}{R_1+R_2+R_3}*R_1
V_2 = \frac{V_Bat}{R_1+R_2+R_3}*R_2
V_3 = \frac{V_Bat}{R_1+R_2+R_3}*R_3
V_1+V_2+V_3 = V_Bat
