Answer:
No.
Explanation:
= Power rating = 1 W
R = Resistance =
V = Voltage =
Power is given by
So
Hence, the resistor is not operating within its power rating.
Answer:
The resistance of the coil is 4 Ω.
Explanation:
The resistance (R) of the coil can be calculated using the following equation:
Where:
ρ: is the resistivity of copper = 0.02x10⁻⁶ Ωm
L: is the length of the coil
A: is the cross-sectional area = 0.8 mm² = 8x10⁻⁷ m²
The length of the coil is given by:
Now, the resistance is:
Therefore, the resistance of the coil is 4 Ω.

Answer:
a) Under damped
Explanation:
Given that system is critically damped .And we have to find out the condition when gain is increased.
As we know that damping ratio given as follows
Where C is the damping coefficient and Cc is the critical damping coefficient.
So from above we can say that
From above relationship we can say when gain (K) is increases then system will become under damped system.
