DC Fundamentals Unit 9 – Series/Parallel Resistive Circuits
Total circuit current flows through series element R1. Total current divides between parallel
elements R2 and R3.
IT and IR1 are identical.
IR1 divides between R2 and R3 based on their values.
IT = IR1 = IR2 + IR3.
The voltage across series elements need not be identical. Voltages across each resistor of a
parallel branch are identical.
VA = VR1 + VR2 or VR1 + VR3
VR2 = VR3
