Principles of Ohms Law - Term Paper Example

The energy can be used to perform actions and do work. This energy can be controlled and manipulated in order to achieve the 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 with 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, the 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 the flow of water. The presence of voltage in a circuit creates a charge which results in the 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 in 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 the 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 a 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, an increase in temperature results in an increase in resistance.

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

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.
