WebA resistor is a passive component that reduces voltage or limits the current flowing through a circuit. This component can also absorb energy and dissipate this energy in the form of heat. Its resistance to the flow of electrons is determined by the conductive materials with which it is built. The materials used in the composition of a resistor ... WebSo what we have calculated is that these two resistors connected in parallel can be replaced by a single resistor of eight ohm. And nothing will change. Everything in the circuit will remain the same. The current in the circuit and the voltage, everything will remain the same. So let's go ahead and do that.
