Question

Problem 19.56 (Multistep) In the circuit shown in the figure below the emf of the battery is 6.6 V Resistor R1 has a resistance of 29 , resistor R2 has a resistance of 47 , and resistor R3 has a resistance of 64 . A steady current flows through the circuit. Part 1 (a) What is the equivalent resistance of R and R2? the tolerance is +/-596 Attempts: 0 of 4 used SAVE FOR LATER SUBMIT ANSWER Part 2 (b) What is the equivalent resistance of all three resistors? the tolerance is +/-5% Attempts: 0 of 4 used SAVE FOR LATER SUBMIT ANSWER Part 3 (c) What is the conventional current through R3? the tolerance is +/-5% LINK TO TEXT Attempts: 0 of 4 used SAVE FOR LATER SUBMIT ANSWER

Explanation / Answer

here, for R1 and R2 in parallel

1)

1/Req = 1/29 + 1/47

Req = 17.9 Ohm

2)

Rnet = R3 + 17.9

Rnet = 64 + 17.9

Rnet = 81.93 Ohm

3)

current through R3 = 6.6/81.93

current through R3 = 0.081 A
