SIGNATURE ____________________________________ (1 point each) True or False The dielectric constant is the ratio of the capacitance of a capacitor using a material between the plates of a capacitor compared to that of the capacitor when there is a vacuum between the plates. True A thermistor is a ceramic semiconductor device which increases its resistivity as the temperature increases and is used to measure and control temperature. False Only cubic crystals can produce a piezoelectric effect where a mechanical force produces an electrical response. False The compound semiconductors are formed by elements from Columns II and VI or III and V of periodic table since their total valence electrons add up to eight. True The compound semiconductor GaAs is an interesting electronic material since the electron mobility is...
