Divider Circuits Kirchhoff's Law

System

The following circuit is usually used as a voltage divider.

 

Figure 1: Voltage divider.

 

Parameters

rr1 = 1k   

[Omega]   

first resistance

rr2 = 2k   

[Omega]   

second resistance

System excitation

The electrical voltage exciting the circuit is E1 = 12sin(10t).

Task

  1. Compute electrical current in the circuit, and electrical voltage across R2.

  2. Using a voltage indicator test the capability of the circuit to ``divide'' electrical voltage.

  3. Verify validity of the voltage Kirchhof's law in the circuit.
