Ohm's law can be written as:

It demonstrates that voltage is equal to the product of current and resistance within an electric circuit.

To solve this problem, use Ohm's law:

Since we are doubling the current, but the voltage is remaining the same, we can set our old and new equations equal to each other.

We know that the second current is equal to twice the first current.

Use this equation to substitute current into the first equation.

The initial current now cancels out from both sides.

Divide both sides by two to isolate the final resistance variable.

The standard equation for power is:

We are given only current and reistance, meaning we must manipulate this equation so that only those variables are present. To do this, we can substitute Ohm's law for voltage.

Now we have an equation for power that uses only current and resistance. Plug in the values given in the question to find the final answer.

By definition, each branch of a parallel circuit will have the same voltage. The current, however, may be split between branches in inequal amounts. In contrast, a series circuit will carry a constant current throughout the circuit, but voltage may differ between elements.

Resistance and capacitance are dependent on the elements present in a given circuit, so no claims can be made. Power is similarly dependent on the elements present in a specific circuit.

A series circuit has the same current running through each component, though the voltage across each component may vary. In contrast, a parallel circuit will carry a constant voltage in each branch and the current may be split in inequal amounts between branches.
