The total number of memory accesses involved (inclusive of the op-code fetch) when an 8085 processor executes, the instruction LDA 2003 is

In Fig., A₁, A₂ and A₃ are ideal ammeters. If A₂ and A₃ read 3 A and 4 A respectively, then A₁ should read

In the circuit of Fig., assume that the diodes are ideal and the meter is an average indicating ammeter. The ammeter will read
