Circuit Analysis | MCQs

Explanation

A circuit is a closed path through which electrons (electric current) flow.

It typically includes components like resistors, batteries, and wires, allowing controlled movement of current.

Explanation

Electronics comprises the:

• Physics: Study of electrons, semiconductors, and electronic behavior.
• Engineering: Design, development, and testing of electronic systems and devices.
• Technology: Application of electronic principles to create devices, circuits, and systems.

Explanation

• Resistance (C) is the opposition to the flow of electric current.
• It is measured in ohms (Ω).

Explanation

• When two bulbs are connected in a series circuit and one bulb blows, the entire circuit is interrupted, and the other bulb will also stop glowing, i.e., also blow (blast).
• This is because there is no longer a complete path for current to flow through the circuit.

Explanation

If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors.

As we've just seen, an increase in plate area, with all other factors unchanged, results in increased capacitanc
