Current and Voltage Divider : 1186818

Calculation By Hand

Considering figure 1 below the voltages and currents will be obtained as follows:

Figure 1: Circuit diagram

  • Finding I1.

First, we obtain the equivalent resistance.

Therefore:

  • Finding V1.
  • Finding V2.
  • Finding I2.
  • Finding I3.
