"In a parallel circuit, the voltage across each branch is the same and equal to the voltage of the source. The total current is the sum of the currents in the individual branches."
"Kirchhoff's current law states that the sum of the currents entering any junction must equal the sum of the currents leaving that junction."

What you'll learn
- Identify a parallel circuit configuration and explain why parallel branches are independent
- Calculate the equivalent resistance of resistors in parallel using 1/R_eq = 1/R₁ + 1/R₂ + ...
