If V = 9 volts and I = 0.5 amps, what is the value of R? _____ohms

Part 2:

Rewrite the equation for I.

18

To find the value of resistance (R), we can use Ohm's Law, which states that the voltage (V) across a resistor is equal to the current (I) flowing through it multiplied by the resistance (R).

So, to find R, we need to rearrange the formula and solve for R:

V = I * R

Given that V = 9 volts and I = 0.5 amps, we can substitute these values into the equation:

9 = 0.5 * R

To solve for R, divide both sides of the equation by 0.5:

R = 9 / 0.5

R = 18 ohms

Therefore, the value of R is 18 ohms.

Part 2:

The equation for current (I) can be rewritten by rearranging Ohm's Law:

V = I * R

We can solve this equation for I by dividing both sides of the equation by R:

I = V / R

So, the rewritten equation for I is:

I = V / R

Just plug your numbers into the equation you already have.
