Q). The unique addresses assigned to the four registers (R1,R2,R3,R4) of the I/O interface are equal to the XX3 , XX7 , XXB and XXF in Hex . Where XX is hex digits equal to your 82 .Show the well labeled external circuit that must be connected between and 12-bit I/O address from the CPU and the CS, RSI, and RS0 Inputs of the Interface
On connecting the two given capacitors, let the final voltage be V.
If capacity of capacitor without the dielectric is C, then the charge on this capacitor is q1=CV
The other capacitor with dielectric has capacity εC.
Therefore, charge on it is q2=εCV
As ε=αV, therefore q2=ε=αV
The initial charge on the capacitor (Without dielectric)
that was charged is q0=CV0
From the conservation of charge, q0=q1+q2
