Current in Resistors connected in Parallel and Series Jointly
Measure current for a set of resistors in series and parallel.
Part of the course: Electricity & Circuits I — DC Fundamentals
Mission
Measure the electric current for a set of resistors in series and parallel
Variables
What you change
- Resistance value
What you measure
- Current
What you keep constant
- Wire length
- Wire cross section
- Battery voltage value
- Temperature of wire
Equations
It = Total current in circuit (A)
I_2 = Current passing through second resistor (A)
I_3 = Current passing through third and fourth resistors (A)
V_Bat ≈ 6 Volts
R_1, R_2, R_3, R_4 = Resistors (ohm)
It=V_Bat*(\frac{R_2+R_3+R_4}{R_2(R_3+R_4)+R_1(R_2+R_3+R_4)})
I_2 =(\frac{V_Bat}{R_2})*(1- R_1\frac{R_2+R_3+R_4}{R_2(R_3+R_4)+R_1(R_2+R_3+R_4)})
I_3 =(\frac{V_Bat}{R_3+R_4})*(1- R_1\frac{R_2+R_3+R_4}{R_2(R_3+R_4)+R_1(R_2+R_3+R_4)})
