Imagine you’re at a fancy party, sipping on some delicious punch. As you mingle with the guests, you notice a curious little trio: voltage, current, and resistance. They seem to be having a lively conversation, and you can’t help but eavesdrop.

Voltage, the most assertive of the trio, booms out, “Hey there, everyone! I’m the boss here, the one who makes the electrical current flow!”

Current, the shy but persistent one, chimes in, “Voltage may be the boss, but I’m the one who actually gets things done. I flow through the circuit, making everything light up and buzz.”

Resistance, the grumpy old man of the group, grumbles, “Well, don’t forget about me, you whippersnappers! I’m the one who slows down the current, making sure it doesn’t get too out of hand.”

Ohm’s Law: The Mathematical Matchmaker

But how do these three friends relate to each other? That’s where Ohm’s Law comes in. It’s the mathematical matchmaker that lets us figure out how voltage, current, and resistance are connected.

The law states that:

Voltage (V) = Current (I) * Resistance (R)

In other words, voltage is like the pressure pushing the current through the circuit, current is like the amount of water flowing, and resistance is like the resistance that the water meets as it flows.
