Ans. 
Types of brick, how to check brick quality, Cement IS code and quality check, Pipe IS code
• Types of bricks include clay bricks, concrete bricks, fly ash bricks, etc.

• To check brick quality, look for uniform shape, size, color, sound when struck, and absence of cracks.

• Cement quality is checked using IS code 12269:1987. Quality can be checked by conducting tests like fineness, setting time, compressive strength, etc.

Q1. What is the impact on phase angle when the frequency of the voltage applied to a series RC circuit is increased?
Ans. 
Phase angle decreases as frequency increases in a series RC circuit.
• As frequency increases, the capacitive reactance decreases, leading to a decrease in phase angle.

• At low frequencies, the capacitive reactance is high, causing a larger phase angle.

• At high frequencies, the capacitive reactance is low, resulting in a smaller phase angle.

Q2. If the frequency of the voltage applied to a series RC circuit is increased, the phase angle decreases.
Ans. 
Yes, as the frequency of the voltage applied to a series RC circuit is increased, the phase angle decreases.
• Increasing frequency means the reactance of the capacitor decreases, leading to a decrease in the phase angle.

• At very high frequencies, the capacitor acts like a short circuit, causing the phase angle to approach zero.

• This phenomenon is important in AC circuits and signal processing applications.
