Tasks for self-training

1. Synthesize an electrical circuit of resistors with a nominal value of 10 ohms, so that the equivalent is 25 ohms
We use the properties of serial and parallel connections




2. Define Uab


3. Determine the readings.


Given: R1 = 2 Ohms, R4 = 3 Ohms,
R5 = 1 Ohm, R3 = 3 Ohms, R2 = 3 Ohms,
E = 75 V

4. Find the equivalent resistance, determine the readings. Determine receiver power and source power. R1 = 10 Ohm, R2 = 10 Ohm, R3 = 20 Ohm, U = 30 V


5. Simplify the scheme


6. To determine the current and voltage in the load, the voltage on the diodes (IVC and Figure 12), if Uin = 4, In Rn = 100, Ohm.
