### Understanding and Using the Equivalent Resistor Calculator

In the world of electronics and circuit design, resistors play a crucial role in controlling current and voltage in various components. When designing complex circuits, it often becomes necessary to calculate the equivalent resistance of multiple resistors connected in different ways. This is where the Equivalent Resistor Calculator comes to the rescue.

### What is Equivalent Resistance?

Equivalent resistance is the single resistance value that can replace a combination of multiple resistors while maintaining the same overall resistance in a circuit. It allows simplification of complex circuits, making analysis and calculations more manageable.

Equivalent resistance is calculated differently depending on how resistors are connected in a circuit. The most common configurations include series and parallel connections.

### Series Resistance

In a series connection, resistors are connected end-to-end, creating a single path for current to flow. To find the equivalent resistance in a series circuit, simply add up the resistance values of all the resistors:

Equivalent Resistance (Series) = R1 + R2 + R3 + ... + Rn

### Parallel Resistance

In a parallel connection, resistors are connected at both ends, creating multiple paths for current to flow. Calculating the equivalent resistance for parallel resistors is a bit more complex:

Equivalent Resistance (Parallel) = 1 / (1/R1 + 1/R2 + 1/R3 + ... + 1/Rn)
