To calculate the B value, multiply the two temperatures (T1 and T2), then divide by the product of the natural logarithm of the ratio of resistances (R1/R2) and the difference in the inverse temperatures (1/T1 – 1/T2).

## B Value Calculator

Enter all values to calculate the B Value

Welcome to the B Value Calculator! This tool helps you determine the B value, which is a measure of temperature coefficient of resistance. Let’s explore how it works and why it’s useful.

The **B Value Calculator** is used to calculate the thermistor’s B value, which describes the relationship between the thermistor’s resistance and temperature. It is commonly used in temperature measurement and control systems. The B value can also appear in other contexts, such as statistics and regression, but in this case, it is focused on thermistors, where the B value is crucial in determining how the thermistor’s resistance changes with temperature.

**Formula:**

`$B = \frac{T_1 \times T_2}{\ln\left( \frac{R_1}{R_2} \right) \times \left( \frac{1}{T_1} - \frac{1}{T_2} \right)}$`

Variable |
Description |
---|---|

B |
B value (thermistor constant) |

T1 |
Temperature 1 (in Kelvin) |

T2 |
Temperature 2 (in Kelvin) |

R1 |
Resistance at T1 (in ohms) |

R2 |
Resistance at T2 (in ohms) |

**Solved Calculation:**

**Example 1:**

Step |
Calculation |
---|---|

Temperature 1 (T1) | 298 K |

Temperature 2 (T2) | 323 K |

Resistance 1 (R1) | 10,000 ohms |

Resistance 2 (R2) | 6,000 ohms |

B Value Calculation |
$B = \frac{298 \times 323}{\ln\left( \frac{10000}{6000} \right) \times \left( \frac{1}{298} – \frac{1}{323} \right)}$ |

Result |
B = 3939.17 K |

**Answer**: The B value is **3939.17 K**.

**Example 2:**

Step |
Calculation |
---|---|

Temperature 1 (T1) | 300 K |

Temperature 2 (T2) | 350 K |

Resistance 1 (R1) | 12,000 ohms |

Resistance 2 (R2) | 8,000 ohms |

B Value Calculation |
$B = \frac{300 \times 350}{\ln\left( \frac{12000}{8000} \right) \times \left( \frac{1}{300} – \frac{1}{350} \right)}$ |

Result |
B = 4010.52 K |

**Answer**: The B value is **4010.52 K**.

### What is B Value Calculator?

A **B Value Calculator** is a tool used to calculate the **b** coefficient in regression analysis. In statistics, the **b value** (also known as the **regression coefficient**) represents the slope of the regression line in linear regression, showing the relationship between the independent variable and the dependent variable.

To calculate the **b value** in simple linear regression, the formula is:

**b = Σ(x – mean of x) * (y – mean of y) / Σ(x – mean of x)²**

This formula calculates the slope of the regression line, which indicates how much the dependent variable (y) changes when the independent variable (x) changes. The **b₀** is the intercept, and **b₁** is the slope, and tools like the **b₀ and b₁ calculator** or **regression coefficient calculator** can help simplify this process.

For **multiple regression**, the **b values** represent the coefficients for each independent variable. You can use tools like the **online multiple regression calculator** to find these values.

**Final Words:**

Last but not least, the** B Value Calculator** can also be used for various applications like **thermistor B value calculations**, which measure temperature sensitivity, or for solving quadratic equations. Additionally, specialized calculators like the **l a b value calculator** or **blox fruits value calculator** exist for other specific uses.
