(3) Oscillator and Rectifier
(4) Inverter and Amplifier
Answers
Answer:
oscillator to inverter
Answer:
The answer is
option [B]. Oscillator and Inverter
Explanation:
Direct current (DC) or alternating current (AC) are both acceptable forms of electricity at the input and output: When the current is flowing in a single, predictable direction, it is called direct current (DC). Typically, it comes from AC/DC converters, batteries, or solar cells. For electrical gadgets, DC power is the recommended source.
A circuit's current flow can take one of two different forms, AC or DC. Electric charge (current) only flows in the same direction with direct current (DC). On the other hand, alternating current (AC) occasionally reverses the direction of electric charge.
The circuit or device known as an oscillator creates repeating signals over a set length of time, or frequency. A phase shift oscillator is the name of this circuit. One type of power electronics—a class of devices that control the flow of electrical power—includes inverters. In essence, an inverter converts a DC input into AC by rapidly flipping the direction of the input. As a result, an AC output is produced from a DC input.
