Resistor Drop Calculator

Formula

The formula to calculate the voltage drop across a resistor is:

\[ V_{drop} = I \times R \]

Where:

(V_{drop}) is the voltage drop across the resistor (V)
(I) is the current flowing through the resistor (A)
(R) is the resistance of the resistor (Ω)

What is a Voltage Drop?

Voltage drop refers to the reduction in voltage across a component in an electrical circuit. It occurs when current flows through a resistive element, such as a resistor, and is an important consideration in circuit design to ensure that each component receives the appropriate voltage.

Example Calculation

Let's assume the following values:

Current ((I)) = 2 A
Resistance ((R)) = 5 Ω

Using the formula:

\[ V_{drop} = I \times R = 2 \times 5 = 10 \]

The Voltage Drop ((V_{drop})) is 10 V.
