Question

Answer both questions.

From Figure 18-5
1) The three resistor that make up R3 as shown in figure 18-5 is an example of resistors connected in __________ and their equivalent resistance is _________ ohms

2) In Figure 18-5 the resistor R1 and R2 connected between points B to D is an example of resistor connected in __________ and the equivalent resistance between points B and D is _____________

The three resistor that make up R3 as shown in figure 18-5 is an example of resistors connected in __________ and their equivalent resistance is _________ ohms In Figure 18-5 the resistor R1 and R2 connected between points B to D is an example of resistor connected in __________ and the equivalent resistance between points B and D is _____________

Explanation / Answer

1. 1/Reff = 1/R1 +1/R2 +1/R3

1/Reff = 1/100 + 1/100 +1/100

1/Reff = 3/100

Reff = R3 = 100/3 = 33.33 ohms

2. series comb ination

Rs = R1 +R2 = 200 +400 = 600 ohms
