... (b) If the resistors have 1% precision, then any resistor Ri can have a resistance as high as 1.01Ri or as low as 0.99Ri . Let’s assume that each resistor takes on a value R = Rnom (1 + ∆) where Rnom is the nominal value, and |∆| < 0.01 is the tolerance (positive or negative). Now re-write the expre ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
