Resistance Formulas:
From: | To: |
Definition: This calculator computes the total resistance for either series or parallel configurations of resistors.
Purpose: It helps electronics engineers, students, and hobbyists quickly determine circuit resistance without manual calculations.
The calculator uses these formulas:
Where:
Explanation: For series circuits, resistances add directly. For parallel circuits, the reciprocals of resistances add together.
Details: Proper resistance calculation is fundamental for circuit design, current flow prediction, and voltage drop analysis.
Tips: Enter resistor values separated by commas, select circuit type (series or parallel), and click Calculate.
Q1: What's the difference between series and parallel circuits?
A: In series, components connect end-to-end (current same, voltage divides). In parallel, components connect across same points (voltage same, current divides).
Q2: Can I mix series and parallel configurations?
A: This calculator handles pure series or parallel. For mixed circuits, calculate sections separately.
Q3: What if one resistor in parallel is 0 ohms?
A: This creates a short circuit - total resistance becomes 0 (not recommended in real circuits).
Q4: How many resistors can I calculate?
A: There's no practical limit - enter as many as needed separated by commas.
Q5: Does order of resistors matter in the input?
A: No, the calculator processes all values regardless of their order in the input.
