Question

Combinations of Resistors-01 n 11 hours minuter Due The figure shows three resistors. R1; 15.5 12, R2.27.7 o, and R,-14.0 . R3 What is the equivalent resistance of the combination of resistors Ra and Rg? Tries 1/10 Previoss Tries 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 dfference (voltage difference) of 8.92 V. What is the total current fiowing from the battery? What is the current lowing through resistor R? Subt Ane Tries 0/1

Explanation / Answer

a] Equivalent resistance of the two resistors in parallel will be:

1/R = 1/27.7 + 1/14

=> R = 9.3 ohms

b] This R = 9.3 ohms is in series with R1 so the equivalent resistance of all the three resistors will be:

Req = 9.3 + 15.5 = 24.8 ohms

c] Current in the circuit is:

i = V/Req = 8.92/24.8 = 0.3596 A

d] Current flowing through R1 will be the same as the total current in the circuit. That is, iR1 = 0.3596 A.
