Working with resistor networks - terminal voltages and curre

Determine the voltage drop across each of the resistors given in the network (See figure). Also determine the unknown resistance R.


Solution Preview

The resistances 5K and 10 K are parallel, the effective resistance is given by ,

[R1 R2/(R1+R2)] = 5x10/5+10 = 3.33 K Ohm

Since the current through the network is given, we can write (using, V/I = R)

1000/100x10^-3 = 3K + 3.33K + R

From this, R = 10000 - 6.33 ...
