Series and Parallel Resistor Networks (Revision) (Grade 12 NSC Matric Physical Sciences): Flashcards

Rate of flow of electric charge, measured in amperes (A)

Energy per unit charge between points, measured in volts (V)

Property opposing charge flow, measured in ohms (Ω)

$I = \frac{V}{R}$

$R_s = R_1 + R_2 + R_3 + \dots + R_n$

Current same throughout: $I_{total} = I_1 = I_2 = I_3$

Voltages add up: $V_{total} = V_1 + V_2 + V_3 + \dots$

$\frac{1}{R_p} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}$

Voltage same across branches: $V_{total} = V_1 = V_2 = V_3$

Currents add up: $I_{total} = I_1 + I_2 + I_3 + \dots$
