Abstract:

Technology never stops from innovating. Modernization goes with it rapidly. Thus education today needs to rise to the call of time through encouragement and equipping of laboratories with trainers which can be used to help students understand the basics in the world of digital electronics. This research is base on the development of a basic electricity trainer whose theory is based on ohm’s law and Kirchhoff’s law.Ohm’s law explore the quantitative relationship between the current through a resistor and the potential difference (voltage) across the resistor. Kirchhoff’s laws are rules used to completely solve a DC circuit. We have experimentally tested Kirchhoff’s Voltage Law and Kirchhoff’s Current Law by measuring the sum of the voltage drops around several closed paths, and the sum of the currents at several nodes, in a resistive circuit made up of three resistors. A low resistance circuit was constructed using resistors 1kΩ,2.2kΩ and 10kΩ Kirchhoff’s Current Law, which states that the algebraic sum of the currents at a node is zero, was found to be accurate to within 1% error. Kirchhoff’s Voltage Law, which states that the algebraic sum of the voltage drops around a closed loop is zero, was found to be accurate to within 1% error when applied to the low resistance circuit. With these we conclude that Kirchhoff’s Laws accurately predict the behavior of resistive circuits.The basic trainer itself is made up of four sections which are the metering section,the power supply section(comprises the variable 0-30V and fixed 5V and 9V),resistor array and components such diodes,zener diodes and thermistor. The trainer is completely recommended for performance Experiments in electrical laboratories.
