Assertion (A): A dual converter may be circulating current type or non circulating current type.

Reason (R): In circulating current dual converter only one converter can be operated at one time.

1. Letters A to Z and a to z
2. Digits 0 to 9
3. Logical operators and, or, not
4. Parenthesis ( )

Assertion (A): Industrial robots improve productivity.

Reason (R): Robots can handle monotonous and complex jobs without error in operation.

1. Current in the circuit is in phase with applied voltage
2. Voltage drop across capacitor C and inductance L are equal in magnitude.
3. Voltage across the capacitor is equal in magnitude to the applied voltage.
4. Current in the circuit is maximum.

1. It should accept an intended transmission without excessive delay
2. The data arriving at a receiving point should be processed rapidly
3. When a transmission calls for a response, the delay of response should be minimum.

1. Taking 2's complement is equivalent to sign change.
2. In the 2's complement representation the most significant bit (MSB) is zero for a positive number.
3. In a 4 bit binary representation of a binary number A, A + 1's complement of A = 2⁴.
