Question

The figure shows three resistors. R1-16.6 , R2=28.5 , and R3-13.7 . What is the equivalent resistance of the combination of resistors R2 and R3? Submit Answer Tries 0/10 What is the equivalent resistance of the combination of all three resistors? Submit Answer Tries 0/10 In this case when finding the total current flowing from the battery, you need to consider the overall, or equivalent, resistance of the circuit. Suppose the voltage source provides a potential difference (voltage difference) of 6.29 V. What is the total current flowing from the battery? Submit Answer Tries 0/10 What is the current flowing through resistor R1? Submit Answer Tries 0/10

Explanation / Answer

a) equivalent resistance of R2 and R3 = R2*R3/ (R2 +R3)

= 28.5*13.7 / (28.5 + 13.7)

= 9.25 ohm

b) R(net) = 16.6 + 9.25 = 25.85 ohm

c) total current = V/R = 6.29 / 25.85 = 0.24 A

d) current through R1 = 0.24 A
