EE2201 Session 2

A __________ is a passive component that resists the flow of electric current, and its resistance is measured in ohms (Ω).

The __________ is a passive component that stores electrical energy in an electric field and its ability to store charge is measured in farads (F).

An __________ is a passive component that stores energy in a magnetic field when electric current flows through it, and its inductance is measured in henries (H).

A __________ is a semiconductor device that allows current to flow in one direction only and is commonly used for rectification.

The __________ is a semiconductor device that can amplify or switch electrical signals and comes in two main types: bipolar junction (BJT) and field-effect (FET).

Your flashlight is not as bright as it used to be, and you suspect the batteries are running low. To confirm this, you decide to measure the __________ across the batteries to see if it has dropped below the rated voltage.

You're setting up a sound system and notice a hum coming from the speakers when no music is playing. To reduce this unwanted noise, you decide to add a __________ across the power supply inputs of the amplifier to filter out the AC ripple from the DC power supply.

Your portable radio stops working, and upon inspection, you find that a component has blown and needs replacement. The schematic indicates that the failed component is an inductor used for tuning to different stations. You need to replace this with a new __________ with the same inductance value as specified in the radio's repair manual.

While working on a solar-powered LED garden light project, you realize the LED is too bright and needs to be dimmed without changing the supply voltage. To achieve this, you decide to insert a __________ with an appropriate resistance value in series with the LED to limit the current flowing through it.

A friend brings you a pedal effects board for an electric guitar that's not working properly. The signal is very weak, and you suspect a problem in the signal amplification path. To fix this, you consider replacing the faulty __________, which is crucial for amplifying the guitar's signal before it reaches the output.
