Assertion (A): If the duty cycle of chopper is low the current would ...
Assertion (A): If the duty cycle of the chopper is low, the current would not become discontinuous.
Reason (R): If the time constant L/R of the load in the chopper is low, the current may become discontinuous.
To understand the correctness of the assertion and reason, let's first define some key terms:
Duty Cycle: The duty cycle of a chopper refers to the ratio of the ON time to the total time period (ON time + OFF time). It is usually expressed as a percentage.
Discontinuous Current: In a chopper circuit, the current is said to be discontinuous when it flows only during the ON time and becomes zero during the OFF time.
Time Constant (L/R): The time constant of a load in a chopper circuit is given by the ratio of the inductance (L) to the resistance (R) of the load.
Now let's analyze the assertion and reason:
Assertion (A): If the duty cycle of the chopper is low, the current would not become discontinuous.
This assertion is incorrect. The duty cycle of the chopper does not directly affect the continuity of the current. The duty cycle determines the ratio of ON time to the total time period, but it does not determine whether the current will be continuous or discontinuous.
Reason (R): If the time constant L/R of the load in the chopper is low, the current may become discontinuous.
This reason is incorrect. The time constant L/R of the load does not determine whether the current will be continuous or discontinuous. The time constant is related to the circuit's response time, but it does not directly affect the continuity of the current.
Based on the analysis above, the correct answer is option 'C' - A is correct but R is wrong. The duty cycle of the chopper and the time constant of the load are not directly related to the continuity of the current.
Reason (R): If the time constant L/R of the load in the chopper is low, the current may become discontinuous.
