Acombined circuit has two resistors in parallel (6.0 ohms and 8.0 ohms) and another in series (13.0 ohms). if the power source is 9.0 volts, what will the current be?
a. 1.3 amps
b. 0.33 amps
c. 0.55 amps d.
2.6 amps

Option C: 0.55 Amps

Explanation:

First find the equivalent resistance for the given circuit:

The two resistors in parallel are equivalent to:

Now we add this to the resistor that is in series (13 ohms) to find the total equivalent resistance for the circuit:

Re = 3.428 ohms + 13 ohms = 16.428 ohms

We use this result to find the current in the circuit by using Ohm's law:

This can be rounded to 0.55 Amps

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
