## Answers ( )

The power is

Explanation:

From the question we are told that

The power delivered is

Let it resistance be denoted as R

The resistors are connected in series so the equivalent resistance is

Considering when it is connected in series

Generally power is mathematically represented as

Here I is the current which is mathematically represented as

The power becomes

substituting value

Considering when resistance is connected in parallel

The equivalent resistance becomes

So The current  becomes

And the power becomes

substituting values
