When commencing to explore the globe of electronics and electricity, it is very important to begin by understanding the fundamentals of voltage (v), current (c) and resistance (R). These three fundamentals are basic building blocks needed to employ and utilize electricity. At first, these concepts may be tough to grasp because we cannot see them. One cannot see with the eye the flowing of energy through a wire.
Even the lightning in the sky, whereas visible, isn’t really the exchange of energy happening from the cloud to the planet.However, a reaction within the air to the energy passing through it. So, as to notice this energy transfer, we should use measurement tools like a spectrum analyzer, multimeter and oscilloscope. This oscilloscope is used to visualize what is happening with the charge in a system. This article will give you the basic relationship and the difference between voltage and current and also relation between current and voltage
Relationship Between Voltage, Current and Resistance
The basic relationship between V, I and R in an electrical circuit is called Ohm’s Law. All materials are made up from atoms, each atom consist of protons, neutrons and electrons. Where protons have a +ve electrical charge, Neutron have no electrical charge and electrons have a –ve electrical charge. These three are together in the atom. But, if we separate them from each other they want to reform to exert a potential of attraction called a potential difference.
When we build a closed circuit, these electrons move and drift back to the protons because of their attraction to create a flow of electrons, this is called electric current. The electrons do not flow freely due to the restriction of flow of electrons, this is called as resistance.
Then all basic circuits comprise of three separate quantities, namely voltage, current and resistance.
Electrical Charge
Electricity is the movement of electrons, it creates charge which we can connect to do the work, your light, phone, stereo, etc. These all are operated using the basic power source that is, the movement of electrons. The three basic principles like voltage, current and resistance can be discussed using electrons or more precisely the charge they create. 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.
Current is the flow of electrons
Resistance is defined as, it is the tendency of a material to restrict the flow of current.
So, when we discuss about these values, the behavior of electrons in a closed loop circuit allows charge to move from one place to another. The major components used in the circuit let us to control the charge and use it to do the work.So, Bavarian scientist “Georg Ohm” was studied electricity. He described a unit of resistance which is defined by voltage and current. The difference between voltage and current and resistance is discussed below
