How is a circuit constructed with five resistors and a battery as shown?
A circuit with five resistors and a battery is constructed by connecting the resistors in series or parallel to create a closed loop for the flow of electric current from the battery through the resistors. The battery provides the energy for the current to flow through the resistors, which resist the flow of current. The arrangement of the resistors and the battery determines the overall resistance and current flow in the circuit.
Is the voltage constant in parallel resistors?
In parallel resistors, the voltage across each resistor is the same, but the total voltage across all resistors may vary.
Do resistors resist voltage or current?
Resistors resist the flow of current in a circuit, not the voltage.
Properties of a resistors?
They are used in circuits and devices commonly (eg.the computer and TV) they slow the amount of electrons going through so that if you are plugged into the mains and have a light bulb that is small, the resistor would be put in place to the device eg.the light bulb doesnt burn out.
Do resistors limit current or voltage in an electrical circuit?
Resistors limit the flow of current in an electrical circuit.
How can you fix a heater and AC fan that only work on high?
Resistors control the speed of the AC/Heater fan. These resistors are switched on and off in various combinations to create the different fan speeds. When the resistors burn out your fan will only work on the "HI" setting. The "HI" setting doesn't use any of the resistors and that's why it works. These resistors are near the blower and the blower is beneath the dashboard on the pasenger side. Just have to located resistors now.
Why would the heating-AC fan on a 1994 Dodge Caravan only run on high?

What are those materials of resistors?
most of the resistors commonly used are carbon resistors
What happens to the value of a resistor when it goes bad?
we can say that a resistor gone bad if 1. its resistance is different than that printed by the color code 2. doesn't conduct any current Resistors normally will burn open. Carbon resistors almost always do this, while wireound resistors can lower in resistance. They may still allow current flow, but it will not be correct.
Does the size of a resistors make a difference in proving ohm's law?
Nope, resistors all the way from 0 ohms through 100 megohms come in the same package size(s). Different package size depends on power rating of the resistor, high wattage resistors must be much larger than low wattage resistors to allow them to dump the heat and not burn out. Some very high wattage resistors even have plumbing fitting attached so that refrigerated cooling water may run through their outer case to help remove heat!
Most common failure in a resistor?
This depends on the type of resistor. Carbon composition and metal film resistors typically will burn open, carbon film types can short.
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
What is the advantage of film resistors over carbon resister?
Film resistors have lower noise than carbon resistors.
What are Resistors wired in series?
Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.
Two resistors are connected in parallel to a battery What must the votlage across these two resistors?
Both resistors will have the voltage of the battery.
Is electric heater require oxygen to burn?
No, electric heaters work by running electric current through resistors which produces heat. same as an element on an oven range top.
When resistors are connected in series then what happens to the watt?
Resistors are rated in wattage so the lowest wattage rating will be the wattage of the series circuit. It will be able to handle that power any more and the lowest wattage resistor could be damaged and fail.Another AnswerWhen two or more resistors are connected in series, the resistor with the lowest resistance will operate at the highest power. If the power developed by a resistor exceeds its rated power, then the resistor may burn out.
