a. To determine Find the values of voltage ( v ) and current ( i ) for the figure shown in 1.6(a) to (d). Explanation Given data: The voltage drop occurs from terminal 2 to terminal 1 is 20 V . The value of current enters the terminal 2 is 4 A . Calculation: From the given data, the polarity reference is drawn as shown below in Figure 1. Refer to Figure 1, the voltage drop occurs from terminal 2 to terminal 1 is 20 V and the current enters the terminal 2 is 4 A . The current entering the terminal 2 is equal to the current leaving terminal 1 ( i . e , 4 A ) . Positive value: The value of voltage is 20 V when the voltage rise from terminal 1 to terminal 2. The value of current is 4 A when the positive charge flows from terminal 2 to terminal 1. The value of current is 4 A when the negative charge flows from terminal 1 to terminal 2. Negative value: The value of voltage is − 20 V when the voltage drops from terminal 1to terminal 2. The value of current is − 4 A when the positive charge flows from terminal 1 to terminal 2. The value of current is − 4 A when the negative charge flows from terminal 2 to terminal 1. Refer to Figure 1.6(a) in textbook, the voltage drop is across the terminal 1 to terminal 2 and the positive charge flows from terminal 1 to 2. Therefore, the value of voltage ( v ) is − 20 V and current ( i ) is − 4 A . Now, the Figure 1.6(a) in textbook is redrawn as shown in Figure 2. Refer to Figure 1.6(b) in textbook, the voltage drop is across the terminal 1 to terminal 2 and the positive charge flows from terminal 2 to terminal 1. Therefore, the values of voltage ( v ) is − 20 V and current ( i ) is 4 A b. To determine Find the value of power associated with the circuit element. c. To determine Find whether the power is absorbed or delivered by the circuit element.
