What makes an interconnection valid?
To be valid, a circuit has to satisfy KVL in all the loops and KCL at all the nodes.
Is the interconnection of ideal sources in the circuit in Figure 1 valid?
Suppose that U1=14 V, U2 =5V,and i-2mA Is the interconnection of ideal sources in the circuit in (Figure 1) valid? No, it is not valid. -Yes, it is valid. Previous Answers Correct Part B Figure 1 of 1 Identify which sources are developing power and which sources are absorbing power.
What are the laws of circuit theory?
Components in a circuit can be connected in one of two ways. The current flowing through every series component is equal. The total resistance (RT) is equal to the sum of all of the resistances (i.e., R1 + R2 + R3). The sum of all of the voltage drops (VR1 + VR2 + VR2) is equal to the total applied voltage (VT).
How do current sources work?
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. 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.
Is the circuit theory of interconnection of sources valid?
Yes, it’s valid. The circuit theory rules here are: Two different ideal voltage sources may not be connected in parallel (across the same pair of nodes). Two different ideal current sources may not be connected in series (in the same branch).
What to do if the interconnection is not valid?
If the interconnection in the Figure is valid, find the total power developed in the circuit. If the interconnection is not valid, explain why. Solution: Problem #2 A variety of current source values were applied to the device shown in the Figure.
What are the laws of interconnection of sources?
The circuit obeys KVL, KCL, and conservation of energy. Putting two voltage sources in parallel violates KVL — the sum of the voltages around the loop is not zero. Putting two current sources in series violates KCL — the sum of the currents entering the node between the sources is not zero.
Why are there two sources in a parallel circuit?
Since current in a series circuit is the same and voltage in a parallel circuit is the same, using two sources is stupid because you can’t have two different numbers equal to each other.
