Answer:
This are the options that applies:
1. Two resistors in parallel can be placed in series with the third.
2.Two resistors in series can be placed in parallel with the third.
3. The resistors can all be connected in series.
4. The resistors can all be connected in parallel.
Explanation:
In an electric circuit, resistors can be connected across each one another either in parallel or in series. Also a series connected resistors can be connected across parallel resistors and parallel connected resistors can be connected across resistors in series in a single circuit.
The net equivalent resistance of this connections is a single resistance that combines all the resistances in a given circuit hence this net resistance cannot be connected across either a series or parallel connected circuits since it is a combination of one or more resistances.
Based on the conclusion above, the following statements are true.
1. Two resistors in parallel can be placed in series with the third.
2.Two resistors in series can be placed in parallel with the third.
3. The resistors can all be connected in series.
4. The resistors can all be connected in parallel.
The other options are false as we cannot connect net resistances to any circuit arrangements.
