Question
Chapter 9, Problem 1RQ
To determine
Kirchhoff’s Voltage law
Expert Solution & Answer
Answer to Problem 1RQ
Refer Fig 9-1.
According to Kirchhoff’s voltage law, the algebraic sum of thevoltage drops and voltage sources around any closed loop must equal zero.
Explanation of Solution
Kirchhoff ’s laws offer the flexibility to solve any type of circuit, especially the circuits with more than one source of power. The laws are applicable for series, parallel as well as series parallel connections.

• We will use the Wattmeter to find the average power supplied/absorbed by each component.
The following figure shows how to connect the Wattmeter to measure the average power
absorbed by the resistor. Note that the Wattmeter consists of a Voltmeter and an Ammeter. The
Voltmeter must be connected in parallel with the component and the Ammeter must be connected
in series with the component. You must pay attention to the polarity of the voltage across the
component as well as the direction of the current flowing through the component.
