Question 229Electricity & Electronics - QMED

The correct answer is A) rectifier. A rectifier is the device used in an electrical circuit to change alternating current (AC) to direct current (DC). Rectifiers work by allowing current to flow in only one direction, effectively converting AC to DC. This is a fundamental requirement for many electrical and electronic devices that need DC power to operate. The other answer choices are incorrect because: B) shunt is a low-resistance connection used to divert current, not convert it. C) current transformer is used to step down current, not convert AC to DC. D) condenser is another term for a capacitor, which does not convert AC to DC.
