Communication Quiz ( 1 - 2 )

What is the main difference between Direct Current (DC) and Alternating Current (AC)?

• DC flows in both directions, while AC flows in one direction.

• DC flows in one direction, while AC changes direction periodically.

• DC is used for large-scale power distribution, while AC is used for small-scale applications.

What does Ohm's Law state?

• V = IR

• P = VI

• I = VR

What unit is resistance measured in?

• Watts (W)

• Volts (V)

• Ohms (Ω)

What is the symbol for an inductor?

• (R)

• (L)

• (C)

What is the function of a diode?

• Amplify signals

• Act as a one-way switch for current

• Store energy in a magnetic field

What does a capacitor store?

• Electric charge

• Magnetic energy

• Heat energy

What is a breadboard used for in electronics?

• Soldering components permanently

• Testing and prototyping circuits without soldering

• Connecting high-power components

What is the purpose of an ohmmeter?

• Measure resistance

• Measure voltage

• Measure current

In a series connection of resistors, how is the total resistance (RT) calculated?

• RT = R1 + R2 + ...

• 1/RT = 1/R1 + 1/R2 + ...

• RT = R1 × R2 × ...

What type of connection results in an effective resistance that is the sum of individual resistors?

• Series connection

• Parallel connection

• Complex connection
