Answer:
Explanation:
plate separation = 2.3 x 10⁻³ m
capacity C₁ = ε A / d
= ε A / 2.3 x 10⁻³
C₂ = ε A / 1.15 x 10⁻³
=
a ) when charge remains constant
energy =
q is charge and C is capacity
energy stored initially E₁=
energy stored finally E₂ =
=
=
=
= 4.19 J
b )
In this case potential diff remains constant
energy of capacitor = 1/2 C V²
energy is proportional to capacity as V is constant .
= 16.76 .
Answer:
Output voltage is 1.507 mV
Solution:
As per the question:
Nominal resistance, R =
Fixed resistance, R =
Gauge Factor, G.F = 2.01
Supply Voltage,
Strain,
Now,
To calculate the output voltage, :
WE know that strain is given by:
Thus
Now, substituting the suitable values in the above eqn:
