Principles of Ohm’s Law Due: Ohm’s Law explains the level of current flow in different amounts of voltage. The phenomenon was coined by Georg S. Ohm in the 19th century. It explains the relationship between Resistance (R), Voltage (V) and Current (I) (Robert, Millikan & Bishop, 2007). Resistance and Current are directly proportional to each other. According to the principle, the interconnection can be compiled in an equation as stated below. This is the building block of electricity energy.

Electricity is movement of charge through electrons. These electrons are usually present in all matter and through their movement, charge is created; which is a form of energy. This energy can be used to perform actions and do work. This energy can be controlled and manipulated in order to achieve most desirable result and to perform a wide array of actions. Through the principles of Ohm’s Law, it has been made possible to control the flow of current by the help of an equation, that is: V = IR (Robert, Millikan & Bishop, 2007).

In order to understand energy, it is important to understand what exactly resistance, voltage and current are. This can be explained through an analogy of a water tank. In this example, charge in this case is the level of water in the tank. The pressure created by this water is voltage and the water flow is the current in a circuit. Water creates pressure in the tank and as a result, there is flow of water. The presence of voltage in a circuit creates charge which results into current. The higher the level of water there is in the tank, the higher the pressure created. Similarly, increasing the amount of charge in the circuit will result into higher current flow through the circuit. The higher the amount of current, the more energy there is. This energy can be used to do work.

In order for current to be created, there has to be a connection through a circuit. A circuit is created when energy flows through a conductor. It can either be broken or complete. This can be done by the use of a switch. Ohm also states that as charge flows through a conductor, it bombards atoms. With increasing voltage, there will ultimately be higher generation of electric charge and therefore there will be more collision of atoms and electrons. This interference is referred to as resistance. When the temperature of the material used for the circuit is increased, the atoms in the material increase their movement and as a result, there is higher bombardment and ultimately higher resistance. Therefore, increase in temperature results in increase in resistance.

According to the Ohm’s Law, current can be altered through by changing the resistance of the circuit (Robert, Millikan & Bishop, 2007). This is achievable through the use of specific components referred as resistors. These components are made of materials whose resistance remains considerably constant within a wide array of temperatures.

The Ohm’s Law also states that another component that is vital in order for one to control a circuit is the switch. The switch is the component that completes a circuit, or alternatively breaks the flow of current in a circuit.
