You can see current flowing in a circuit, yet voltage, current, and resistance can feel unrelated. Think of a household tap. Water pressure pushes water through the pipe. That pressure is like voltage: it provides the push. Water flowing is like current. If the pipe becomes narrow, less water gets through. That is like resistance: more resistance means less current. Now the pipe comparison becomes an electrical relationship. This is Ohm's law: voltage, V, equals current, I, times resistance, R-R-V equals I times R. To find current, rearrange the same relationship: I equals V divided by R. Keep resistance the same, and increasing voltage increases current. Keep the voltage the same, and increasing resistance decreases current. In steady conditions, this rule connects the three measurements. Remember the tap: voltage is pressure, current is flow, and resistance is blockage. Divide voltage by resistance to find current: I equals V over R.
