How to calculate resistance of resistors in parallel Resistors R₁ and R₂ in parallel When resistors are connected in parallel , the total resistance can be calculated using the formula: ...

This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t} &=& \frac{3.9 \times 6.8}{3.9 + 6.8} \\ &=& ...
