Voltage Doubler Circuits: Both full wave and half wave rectifier circuits produce a d.c. voltage less than the a.c. maximum voltage. When higher d.c voltages are needed, a Voltage Doubler…
Half and Full Wave Rectifier Circuits: Half and Full Wave Rectifier CircuitsĀ for producing high d.c. voltages from a.c. sources may be (a) Half wave, (b) Full wave, or (c) Voltage…
Applications of Cables in Engineering Works: In the recent years natural rubber has been completely replaced by synthetic rubbers and plastics as cable insulation. The physical properties required for wire…
Applications in Circuit Breaker: Applications in Circuit Breaker : A circuit breaker is a switch which automatically interrupts the circuit when a critical current or voltage rating is exceeded. A.c.…
High Temperature High Performance Polymers: High Performance Polymers films are thermoplastic and are generally transparent. The are needed for use in applications where temperatures vary from very low (- 269Ā°C)…
Breakdown in Composite Dielectrics: It is difficult to imagine a complete insulation system in an electrical equipment which does not consist of more than one type of insulation. If an…
Experimental Arrangement to Measure Ionization Coefficients Ī±Ā and Ī³: The Experimental Arrangement to Measure Ionization Coefficients is shown in Fig. 2.2. The electrode system consists of two uniform field electrodes. The…
Townsend Current Growth Equation: Referring to Fig. 2.1 shows theĀ Townsend Current Growth Equation. let us assume that n0Ā electrons are emitted from the cathode. When one electron collides with a neutral…
