Solve the following table given: Ohm's Law formula and that all voltage (E) values are equal to 120V.

Question

Ohm's Law I = E/R (I = current, E = Voltage, R = Resistance)

Et =120V It = 24 A Rt = 5 ohms
E1 =120V I1 = R1 = 15 ohms
E2 = 120V I2 = 12A R2 =
E3 = 120V I3 = R3 = 30 ohms

Answer 1

To solve for the missing values, we can use Ohm's Law formula: I = E/R

E2 = 120V, I2 = 12A
Using the formula, we can rearrange it to solve for R2:
R2 = E2/I2
R2 = 120V/12A
R2 = 10 ohms

Therefore, the missing value is R2 = 10 ohms.
