Correct Answer : Option (A) : Cathode current
Explanation : SCR stands for Silicon Controlled Rectifier. Once the SCR is turned on, it will remain in the same conducting state until the anode current becomes lower than the holding current.
Correct Answer : both inverter and rectifier
Explanation : Rectifier to converter the dc from the battery to ac. Inverter to charge the battery from mains.
Correct Answer : smaller conductor size
Explanation : The conductor size is smaller as there is no sink effect, and the whole conductor is utilized for transmitting power.
Correct Answer : Chopper
Explanation : SMPS (Switching mode power supply) are based on the chopper principle. The output dc voltage is controlled by varying the duty cycle of the chopper circuit.
