A battery E (e.m.f 12v and internal resistance 0.8 ohms) and a resistor R1 (10 ohms) are connected in series across two parallel resistors (R2 = 12 ohms, R3 = 18 ohms).
i) Draw the circuit diagram, determine the battery terminal voltage.
ii) Calculate the powers P1 and P2 dissipated across R1 and R2 respectively

How many bits are the virtual and physical page numbers

Consider a virtual memory system that can address a total of 232 bytes. You have unlimited hard drive space, but are limited to only 8 MB of semiconductor (physical) memory.
