Why I Kept Messing Up Ohm’s Law

Was getting frustrated because Ohm’s Law is supposed to be “easy” but I kept messing it up.

What I was messing up:

- Not paying attention to units

- Mixing up watts, volts, and amps

- Plugging numbers in without thinking

What clicked:

It wasn’t the formula—it was the units.

Once I slowed down and asked:

“What am I solving for?”  

“What units should the answer be in?”

Everything started lining up.

Also started double checking:

Volts × Amps = Watts

If that didn’t make sense, I knew I messed up somewhere.

Takeaway:

Ohm’s Law isn’t hard—the discipline is.

Next step:

Keep practicing but focus on units every single time.
