Aov International Biomedical Engineer Interview Questions and Answers

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

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

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• It is named after the German physicist...read more

Impedance is the measure of opposition to the flow of alternating current in a circuit.

• Impedance is a complex quantity that includes both resistance and reactance.

• It is measured in ohms and is represented by the symbol Z.

• Impedance can be calculated using the formula Z = R + jX, where R is the resistance and X is the reactance.

• In AC circuits, impedance affects the flow of current and voltage.

• Impedance matching is import

A diode is a semiconductor device that allows current to flow in one direction only. AC can be converted to DC using rectifiers. Microprocessors process data using logic circuits. Transistors amplify or switch electronic signals. AC motors run on alternating current while DC motors run on direct current. Power supplies can work with both AC and DC inputs. Resistance is the opposition to the flow of electric current. Re...read more

Relays are electrically operated switches used to control high power devices with low power signals.

• Relays consist of a coil, an armature, and one or more contacts.

• When current flows through the coil, it creates a magnetic field that attracts the armature, closing the contacts.

• Relays are commonly used in control circuits to switch high power devices such as motors, lights, and heaters.

• They can be used to isolate contro...read more

Power can be converted from AC to DC using a rectifier circuit.

• Use a rectifier circuit to convert AC to DC

• Rectifier circuit consists of diodes which allow current to flow in one direction only

• Examples of rectifier circuits include half-wave, full-wave, and bridge rectifiers
