# Dc Voltage Drop Calculator

This Dc Voltage Drop calculator estimates the voltage drop of an electrical circuit based on wire size, distance, and expected load current. Please note that this calculator assumes that the circuit is operating at room temperature.

### What is Dc Voltage Drop?

In order to calculate the voltage drop in an electrical circuit, the voltage drop formula is utilised. The decrease in electric potential as the electric current passes through the circuit is known as voltage drop. Impedance is what causes the voltage in the circuit to drop.

The Dc voltage drop formula is as follows:**V = IR**

Where,

- The voltage drop in the circuit is denoted by V.
- The current flowing across the circuit is denoted by I.
- R stands for resistance.

### Dc Voltage Drop Calculation Examples

**Question 1:** Calculate the Dc voltage drop if a wire with a resistance of 3 ohms receives a 40 Ampere current.

**Solution:**

Consider the question, we have

I is the current 40 A

Resistance R is 3 ohms

The voltage drop is caused by the formula: **V=IR**

V=(40)(3)

V=120 volts.

Therefore, The Dc voltage drop is **120volts**.

### FAQs on Dc Voltage Drop Calculator

**1. What is formula for calculating the Dc voltage drop?**

The Dc voltage drop formula is as follows: **V=IR**

Where,

- The voltage drop in the circuit is denoted by V.
- The current flowing across the circuit is denoted by I.
- R stands for resistance.

**2. Is there a voltage drop while working with Dc?**

Both the supply and return wires of a circuit have voltage drop. Voltage equals current multiplied by resistance in a Dc circuit.

**3. What exactly is a Dc drop?**

The decrease in electric potential as the electric current travels through the circuit is known as voltage drop. Impedance that's what causes the voltage in the circuit to drop.

**4. What causes a dip in Dc voltage?**

When the voltage at the end of a network run is lower than it was at the beginning, this is known as voltage drop (VD).
