Chapter 21: Q35PE (page 776)

Apply the junction rule at point a in Figure 21.52.

Short Answer

Expert verified

Using the junction rule on point 'a', we obtained:

I3=I2+I1

Step by step solution

01

Definition of Kirchhoff's law

Kirchhoff's first law defines currents at circuit junctions. It states that the sum of currents flowing into and out of a junction in an electrical circuit equals the sum of currents flowing out of the junction.

02

Explanation for the junction rule

The sum of currents entering the junction equals the sum of currents leaving the junction, according to the junction rule. An equation may be written for point an in the figure 21.55 using the following rule:

I3=I2+I1

Hence current at location 'a' can be calculated using Kirchhoff's Junction rule as follows:

I3=I2+I1

Most popular questions from this chapter

The \({\rm{RC}}\) time constant in heart defibrillation is crucial to limiting the time the current flows. If the capacitance in the defibrillation unit is fixed, how would you manipulate resistance in the circuit to adjust the \({\rm{RC}}\) constant \(\tau \)? Would an adjustment of the applied voltage also beaded to ensure that the current delivered has an appropriate value?

Why should you not connect an ammeter directly across a voltage source as shown in Figure21.48?(Note that script Ein the figure stands for emf.)

Verify the third equation in Example 21.5 by substituting the values found for the currentsl1andl3.

Apply the junction rule to junction b in figure below. Is any new information gained by applying the junction rule at \({\rm{e}}\)? (In the figure, each emf is represented by script \({\rm{E}}\).)
