Quizplus · Accepted Answer

When resistors are connected in parallel, the equivalent resistance is calculated using the formula: 1/Req = 1/R1 + 1/R2 + 1/R3 + ... 
In this case, the equivalent resistance can be calculated as:
1/Req = 1/330 + 1/270 + 1/68
1/Req = 0.00909
Req = 110
Therefore, the closest answer is D, 47Ω.

If a 330 Ω\OmegaΩ Resistor, 270 Ω\OmegaΩ Resistor and 68
