1003-C: Analyze Circuits 1

BACK to Ladder DC Circuit Math 1: Batteries and Resistors

In the level 1 sections, we determined how to calculate the voltage, current, resistance, and power of a circuit with just a battery and a single resistor using two formulas: $$ V = IR $$, $$ P = IV $$. In this section, we will determine the voltage, current, resistance, and power of each resistor within a circuit. Based on how the circuit is connected, these quantities follow logical mathematical rules.

There are two ways for a circuit to be connected called series and parallel circuits. Each of these circuits follows particular rules.

Solving a Series Circuit

Series Circuit Rules:

Solving a Parallel Circuit

Parallel Circuit Rules:
  1. What rule is the same for series and parallel circuits?
  2. What rules are different for series and parallel circuits?

Solving for Power of Circuits

Power Rule

In all circuits, series or parallel, you can use the formula \( P = IV \) to find power.
