State, with reasons, whether the following statements are True or False.

i) Ideal voltage source has infinite internal resistance.

ii) Transformer is a passive device hence it cannot increase the voltage.

iii) Field effect transistor (FET) is a current controlled device.

iv) Forward biasing of a semiconductor junction diode reduces its energy band gap.

v) Amplifier with common collector mode offers maximum voltage gain.

vi) Ripple factor of a center tapped full wave rectifier is greater than that of a bridge rectifier, which uses four diodes.

vii) Operational amplifier in non-inverting mode cannot amplify negative signals.

viii) IC LM380 is a small signal amplifier used to amplify the voltage.

ix) Largest decimal number represented by a 2-digit hex number is 99.

x) In a CRO sweep generator output is given to the vertical deflection plates.

i) False. An ideal voltage source has zero internal resistance, not infinite.

ii) False. A transformer is a passive device, but it can increase or decrease the voltage depending on the turn ratio.
