VDOIT4U Event Management Interview Questions and Answers

A step-up transformer increases voltage while a step-down transformer decreases voltage.

• Step-up transformer has more turns in the secondary coil than in the primary coil

• Step-down transformer has fewer turns in the secondary coil than in the primary coil

• Step-up transformers are used in power transmission lines to increase voltage for long-distance transmission

• Step-down transformers are used in household appliances to decrease voltage for safe use

AC is converted to DC using a rectifier, which changes the flow of current from bidirectional to unidirectional.

• Use a rectifier to convert AC to DC

• Rectifiers can be half-wave or full-wave

• Examples of rectifiers include diodes and thyristors

DC to AC conversion is done using an inverter, while AC to DC conversion is done using a rectifier.

• DC to AC conversion involves using an inverter to convert the steady flow of direct current into a fluctuating flow of alternating current.

• AC to DC conversion involves using a rectifier to convert the alternating current into direct current.

• Inverters use electronic components like transistors and capacitors to switch the polarity of the DC input to create an AC output.

• Rectifiers...read more

An RLC circuit is a circuit composed of a resistor, inductor, and capacitor, used in electrical engineering for various applications.

• An RLC circuit can be used in filters, oscillators, tuners, and frequency mixers.

• The behavior of an RLC circuit is governed by the values of resistance, inductance, and capacitance.

• The impedance of an RLC circuit varies with frequency, leading to different responses in AC circuits.

• Examples of RLC circuits include bandpass filters, low-pass filte...read more
