Question

True or False 1.The equivalent resistance for two resistors in 2.The equivalent resistance for two resistors in 3.The total current going through two resistors in 4.The total current going through two resistors in series can be found this way: 1/Reg- 1/Ri +1/R:2 parallel can be found this way: 1/Rea 1/Ri +1/R2 parallel is equal to the sum of the current going through each individual resistor: 1 = 1 1 + 12. series is equal to the sum of the current going through each individual resistor: 1 = 1 1 + 12. 5.When bulbs are in series, the failure of one will 6.When filaments are in parallel, the failure of one 7.When multiple resistors are in parallel, the cause the entire circuit to break (no current). will not affect others current will take all branches, not only the branch with the least resistance. But the branch with the least resistance will get the largest amount of current. 8.When multiple branches are in parallel, if one branch only has ideal wire, the resistance is zero, the current will only take the zero

Explanation / Answer

1. when in series,

Req = R1 + R2

False

2. in parallel, 1/Req = 1/R1 + 1/R2

True

3. Using KCL, I = I1 + I2

True

4. in series, current will be same through both.

I = I1 = I2

False

5. when series, I1 = 0 then I1 = I = I2 = 0

True

6. True,

7. for parallel branches, Potential drop across them will be same as V.

so I = V / R

for least R, I will be greatest.

True

8. true.

current will flow through only ideal wire.
