That electricity is handled in circuits: aclosed loop of conductors travelling from power plants to neighborhoods to households andback again. That closed loop, with all of its many parts, forms one huge electrical circuit.Electricity is very useful when it comes to medical field as it used in various important aspectswhich include saving the life of an individual using life saving machine, used to make an artificialheart in case of heart failure, diagnose certain disease used in telemedicine among othersOne of the fundamental laws describing how electrical circuits behave is Ohms law. Accordingto Ohms law, there is a linear relationship between the voltage drop across a circuit elementand the current flowing through it. Therefore the resistance R is viewed as a constantindependent of the voltage and the current. In equation form, Ohms law is:V = IR.V is the voltage applied across the circuit in volts (V), I is the current flowing through the circuitin units of amperes (A), and R is the resistance of the circuit with units of ohms ().
