Answer:
Resistivity = 231.481 K Ohm
Yes, Intrinsic Silicon is the semiconductor.
Explanation:
Solution:
At 300K:
Let suppose mobility of electron in intrinsic semiconductor =
Mobility of electron in intrinsic semiconductor is:
= 1300
/volt.sec
Let suppose mobility of hole in intrinsic semiconductor =
= 500
/volt.sec
We know that, intrinsic silicon semiconductor has equal number of holes and electrons. So,
At 300 K
Intrinsic Carrier Concentration = 1.5 x /
= C
And,
Conductivity of intrinsic Silicon is:
σ = C x ( +
) e
e = 1.6 x C
So, plugging in the values, we get:
σ = C x ( +
) e
σ = 1.5 x x (500 + 1300) x 1.6 x
σ = 4.32 x
So, now we can find the resistivity.
Resistivity = 1/σ
Resistivity = 1/ 4.32 x
Resistivity = 231.481 K Ohm
Yes, Intrinsic Silicon is the semiconductor.
Answer:
Explanation:
Given:
Charge = <em>q</em>
Electric field strength =
weight of the droplet = <em>mg</em>
The charge is suspended motionless. This is because the electric force on the charge is balanced by the weight of the droplet.
electric force on charged droplet,
This is balanced by the weight,
Equating the two:
