Electronics and Communication Electronic Devices And Circuits Difficulty: Medium

The most common detector used in an AM radio broadcast receiver is: Electrical charge flows from . . . . . . . . . An RC circuit has an R of 10 kΩ and C = 0.05 µF. The applied voltage for charging is 36 V. How long will it take C to charge to 24 V? For 555 astable multivibrator, if C = 0.01 µF, R A = 10 kΩ, R B = 50 kΩ, the frequency and the duty cycle will be nearly. In 8051, the accumulator register contains 80H and B register contains 8FH. The content of the accumulator and status of the carry flag after the addition operation are respectively,
