# What Is The Relationship Between Current And Voltage?

Current and voltage are two fundamental quantities in electricity. Voltage is the cause and current is the effect. The voltage between two points is equal to the electrical potential difference between those points. It is actually the electromotive force (emf), responsible for the movement of electrons (electric current) through a circuit.

## What is the difference between current and voltage?

The main difference between current and voltage is, if a potential difference is applied b/n two points in any material, in principle, current can exist. Voltage is defined as, it is the potential difference b/n two points in electrical charge.

## What is the relationship between voltage and current in a resistor?

Then the voltage across a conducting material is directly proportional to the current flowing through the material and the relationship between voltage, (V) and current, (I) in which the resistance, (R) is constant is called the constant of proportionality.

## How to plot the relationship between current and voltage?

Connect the circuit as shown in the diagram above. Record the readings on the ammeter and on the voltmeter. Record the new readings on the ammeter and the voltmeter. Plot a graph of current (y-axis) vs voltage (x-axis), which should look like this.

## How are voltage and current related in ohm's law?

V = I*R, I = V/R, and R = V/I Were: I is the current, V is the voltage and R is the resistance. In its simplest form, Ohm’s law states that the current flowing through a resistor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them.

#### Can You Replace A Fuse With A Higher Voltage?

I know from reading elsewhere that it's safe to use a fuse with a higher voltage rating when replacing one, so long as the current rating and reaction speed is the same. For example, if a fuse is rated 125V 1A, then a 250V 1A can be used. Let's say these two example fuses have a resistance of 0.153 and 0.237 ohms, respectively.

#### Do Resistors Reduce Current Or Voltage?

A resistor has the ability to reduce voltage and current when used in a circuit. The main function of a resistor is to limit current flow. Ohm’s law tells us that an increase in a resistors value will see a decrease in current. To reduce voltage, resistors are set up in a configuration known as ‘voltage divider’.
