Consider the sections of two circuits illustrated above. Select True or False for all statements. After connecting c and d to a battery, the current through R3 always equals the current through R4. Rcd is always less than or equal to R3. After connecting a and b to a battery, the voltage across R1 always equals the voltage across R2. Rab is always less than or equal to R1.

Follows are the solution to the given question:

Explanation:

In this question the missing file of the circuit is not be which is defined in attached file please find it.

In Option 1, this statement is true because the current is on , that is the same.

In option 2, this statement is false because therefore it implies that Rcd is always larger then .

In option 3,  this statement is true because the voltage of is always equal.

In option 4, this statement is true because is always smaller then 1 therefore, is always equal to R1.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

d) physical means can be used to separate the components of air.
