Resistor In Physics. Resistor is defined as a passive electrical component with two terminals that are used for either limiting or regulating the flow of electric current in electrical circuits. A for a series connection of resistors the current is the same in each resistor.
The resistor is like a pipe that reduces pressure and limits flow because of its resistance. When resistors are connected in series the total of all the potential differences sometimes referred to simply as voltage around the circuit is equal to the potential difference p d of the. Each resistor thus has the full voltage of the source applied to it.
Wires of negligible resistance to carry current i on a closed loop from the voltage source to the resistor and back.
The voltage source supplies energy causing an electric field and a current and the resistor converts it to another form such as thermal energy. When resistors are connected in series the total of all the potential differences sometimes referred to simply as voltage around the circuit is equal to the potential difference p d of the. The sum of the individual currents equals the current that flows into the parallel connections. Resistors are in parallel when each resistor is connected directly to the voltage source by connecting wires having negligible resistance.
