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
