The Kenya Certificate of Secondary Education (KCSE) is an academic certificate awarded to candidates upon completion of secondary education in Kenya. [1]The first KCSE exam was held in 1989 at the same time as the last Kenya Advanced Certificate of Education (KACE), which it replaced as the entrance requirement for Kenyan universities.
The examination was supervised by the Kenya National Examination Council (KNEC), an examining body in Kenya under the Ministry of Education. The same body also conducted and regulated the Kenya Certificate of Secondary Education (KCSE), a certificate awarded to students after completing secondary education. KCPE and KCSE were both started in ...

A bridge circuit is a topology of electrical circuitry in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging ...
Since 1938, although the aim of the IEV remains unchanged – to provide precise, brief and correct definitions of internationally accepted concepts in the field of electrotechnology, electronics and telecommunications – the scope of the IEV has expanded in line with the expansion of the electrotechnical industry.
Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves . In modern systems, the conversion is performed with semiconductor switching devices such as diodes , thyristors , and power transistors such as the power MOSFET and IGBT .
In electronic systems, power supply rejection ratio (PSRR), also supply-voltage rejection ratio [1] (k SVR; SVR), is a term widely used to describe the capability of an electronic circuit to suppress any power supply variations to its output signal.
In the field of power electronics the reduction of the effect of changes of influence quantities on the output quantity. stabilized power supply In the field of power electronics an equipment which takes electrical energy from a source and supplies it stabilized by means inside the equipment to one or more pairs of output terminals.
