1688 - What is Ohm's Law regarding voltage, current, and resistance?

Ohm's Law is like a math formula that helps us understand how electricity works. It says:

Voltage (V) equals Current (I) multiplied by Resistance (R).

The formula is: V = I x R

Think of it like water flowing through a hose:

• Voltage (V) is like the water pressure.
• Current (I) is like the amount of water flowing.
• Resistance (R) is like how narrow or blocked the hose is.

If you know any two of these things (V, I, or R), you can use the formula to figure out the third one!
