# How do you convert voltage to resistance?

## How do you convert voltage to resistance?

So volts are equal to the square root of watts times ohms:

1. volts = √watts × ohms. or.
2. V = √W × Ω Example. Calculate the voltage V in volts when the resistance is 12.5Ω and the power is 2 watts.
3. V = √2W × 12.5Ω = 5V. How to convert volts to ohms ► See also.

## What is voltage resistance and current?

Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material’s tendency to resist the flow of charge (current).

How are voltage V current I and resistance R related?

The relationship between voltage, current, and resistance is described by Ohm’s law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.

### What is the internal resistance of a 3.0 V battery?

A 3.0 V battery has an internal resistance of 0.5 ohms and is connected to a load resistor of 4 Ω. What is the current in the circuit and the terminal voltage? 8 clever moves when you have \$1,000 in the bank.

### How is the resistance of a circuit related to the current?

Ohm’s Law is one of the most basic and important electric and electronic circuit laws. Ohm’s Law states that the current flowing into a circuit is directly proportional to the potential difference and inversely proportional to the circuit resistance. Ohm’s Law symbol is denoted by Ω letter.

What is the resistance of a 4.0 ohm resistor?

A 4.0 Ohm resistor is connected as a load. The total resistance around the loop is Rt = 0.5 + 4.0 = 4.5 Ohms. The terminal voltage is Vt = 3.0v – 0.5 Ohms x 2/3 Amp = 3.0v – 0.333v = 2.667v.

#### How does Ohms Law relate to current and resistance?

Georg Simon Ohm expressed his discovery in the form of a simple ohm’s law equation that describes how voltage, current, and resistance interrelate: In this ohms law equation – voltage (V) is equal to the current (I) multiplied by resistance (R).
