Rectifier diagram converts AC to DC by removing negative half cycles.

• Rectifier circuit consists of diodes and transformer.

• AC voltage is applied to the transformer which steps down the voltage.

• Diodes are used to remove the negative half cycles of the AC voltage.

• The output obtained is a pulsating DC voltage which can be smoothed using a filter circuit.

• AC rectifier diagram includes half-wave and full-wave rectifiers.

• DC rectifier diagram includes center-tap and bridge rectifiers.

A rectifier is an electronic device that converts AC to DC.

• Rectifiers are used in power supplies to convert AC voltage to DC voltage.

• They are commonly used in electronic devices such as radios, televisions, and computers.

• There are two types of rectifiers: half-wave and full-wave.

• Half-wave rectifiers only allow half of the AC waveform to pass through, while full-wave rectifiers allow the entire waveform to pass through.

• Rectifiers can be made using diodes or other semiconductor...read more

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It applies to conductors that are linear and have a constant temperature.

• Ohm's law is used in electrical engineering to calculate the current, voltage, or resistance in a circuit.

• For example, if the voltage across a resistor is 1...read more

A multimeter is a device used to measure electrical properties such as voltage, current, and resistance.

• A multimeter typically has a display screen, probes, and a dial or buttons to select the type of measurement.

• To measure voltage, the probes are connected to the circuit and the dial is set to the voltage range.

• To measure current, the multimeter is placed in series with the circuit and the dial is set to the current range.

• To measure resistance, the probes are connected to th...read more
