C. Number
Explanation:
If you're doing a relational comparison, a number filter would be available.
The answer is;
Current
Voltage
Power/Wattage
Circuit
Water moving through pipes is like electricity flowing in a circuit. The flow of electricity is an actual flow of electrons. That movement of electrons is what is known as current. Think of current as the volume of water flowing through a water pipe. The electrons need some force or pressure to move, and so is water in a pipe. The voltage is that electromotive force; the pressure that pushes the electrons in a system. The power measured in Watts is the rate at which the energy is consumed. For the current to flow the circuit must be complete. Otherwise we cannot say that we have power if the circuit is not closed.
