boo_lufc said:I have got:
I1 = 0.782mA
I2 = 0.955mA
I3 = 1.391mA Do these seem right?
When I use these values to work out the current across R2 for example I get the same value but negative and positive depending on what loop eqn I use. This seems like it would be right but in terms of the question: Find all the currents in the cct: how would I present this as a current in the cct?
Kirchoff's Laws are a set of rules used to analyze electric circuits. They are based on the principles of conservation of charge and conservation of energy. These laws are used to find all the currents flowing in a circuit by applying the concepts of voltage, current, and resistance.
The first law of Kirchoff, also known as the Current Law or Kirchoff's Junction Rule, states that the sum of currents entering a junction in a circuit must equal the sum of currents leaving that junction. This law helps in finding currents in a circuit by providing a mathematical equation to solve for unknown currents.
Kirchoff's second law, also known as the Voltage Law or Kirchoff's Loop Rule, states that the sum of voltage drops in a closed loop circuit must equal the sum of voltage rises. This law is useful in finding currents in a circuit by providing a way to calculate unknown voltages and currents using Ohm's Law.
Yes, Kirchoff's Laws can be applied to any type of circuit, whether it is a simple series or parallel circuit, or a more complex network of circuits. These laws are applicable to both DC and AC circuits.
While Kirchoff's Laws are an essential tool for analyzing circuits, they do have some limitations. These laws assume that the circuit is in a steady state, meaning that all the voltages and currents in the circuit are constant. They also assume that the circuit components are linear, meaning that the relationship between voltage and current follows Ohm's Law. In some cases, these assumptions may not hold true, and other methods may be needed to analyze the circuit.
