Q1:

Which statement is correct?

A BJT and MOSFET are current controlled devices

B BJT is voltage controlled and MOSFET is current controlled device

C BJT and MOSFET are voltage controlled devices

D BJT is current controlled and MOSFET is voltage controlled device

ANS:D - BJT is current controlled and MOSFET is voltage controlled device

BJT is controlled by its base current and MOSFET is controlled by its gate voltage. Hence, BJT is a current controlled device and MOSFET is a voltage controlled device.
