* Voltage (V): Voltage is the electrical "pressure" that pushes electrons through a circuit. It's like the water pressure in a pipe. Resistance doesn't *increase* voltage; it's the voltage that *drives* the current.
* Current (I): Current is the flow of electrons through a circuit. It's like the amount of water flowing through the pipe. Resistance *limits* the current flow. Think of it like a narrow pipe restricting the water flow.
Ohm's Law explains the relationship between voltage, current, and resistance:
* V = I * R
Where:
* V is voltage (measured in volts)
* I is current (measured in amps)
* R is resistance (measured in ohms)
Here's what this means:
* Higher resistance (R) means lower current (I) for a given voltage (V). If you increase the resistance of a circuit while keeping the voltage constant, the current will decrease.
* Lower resistance (R) means higher current (I) for a given voltage (V). If you decrease the resistance of a circuit while keeping the voltage constant, the current will increase.
In summary: Resistance opposes the flow of current. It doesn't make voltage or current higher; it limits the current flow for a given voltage.
