When an electron is displaced in a semiconductor, the hole that's left behind is

a. attracted to the negative terminal of the voltage source.
b. incapable of carrying a charge.
c. attracted to the anode of the voltage source.
d. considered an impurity in the crystal.

A. attracted to the negative terminal of the voltage source.

Explanation:

When an electron is displaced in a semiconductor, the hole that's left behind is

A. attracted to the negative terminal of the voltage source.

The electron leaving leaves a net + charge, which is attracted to the negative terminal.

its c its is a mixture of gases

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
