cuz a resistor is basically a long wire , that resists some of the charges flowing across it.
it has resistive properties which stops some of the current from flowing from one terminal to the other.
so....as it is just a piece of wire....it doesn't need a +ve or a -ve terminal
What else can I help you with?
What does positive of the coil mean?
The COIL HAS A POSITIVE AND A NEGATIVE TERMINAL. If you look at the top of the coil, it is generally marked + and - on the top.
What determines which one of the terminal of a rheostat in positive when connected in a series?
Electron flow is from negative(-) to positive(+), the rheostat would have to be on the negative side for the device being controled, before the device, e.g. light bulb.AnswerIt doesn't matter. Rheostats don't have positive or negative terminals.
What is the center terminal of a variable resistor called?
The center terminal of a variable resister is called a wiper.
Are 1952 ford f1 pickups positive ground?
Yes, the 1952 Ford F1 pickups were originally equipped with a positive ground electrical system. This means the positive terminal of the battery was connected to the chassis, and the negative terminal was connected to the electrical components. However, many owners have since converted these trucks to negative ground systems for compatibility with modern accessories and components.
Why do telecommunication systems use negative voltage?
negative polarity is achieved by grounding the positive terminal of power supply system and the battery bank. This is done to prevent electolysis depositions.
What are the colours of the positive and the negative terminals of the rheostat?
A rheostat is simply a variable resistor used to control current. It does not have a positive or a negative terminal.
How do you know positive and negative terminals?
Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which,
Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
Does energy flow through the negative or positive of a battery?
Energy flows from the negative terminal to the positive terminal of a battery.
What happens when you inadvertanly crossed the positive battery terminal from a negative to a positive and a positive to a negative.?
What happens when you inadvertently crossed the positive battery terminal from a negative to a positive and a positive to a negative.?Read more: What_happens_when_you_inadvertanly_crossed_the_positive_battery_terminal_from_a_negative_to_a_positive_and_a_positive_to_a_negative.
What does the negative terminal of a battery have?
The negative terminal of a battery has a - sign and positive terminal has a + sign.
What is positive about batteries?
One terminal is positive and the other terminal is negative. The positive terminal is slightly larger.
Does the positive end of a battery go to the positive or negative end of the terminal?
The positive end of a battery goes to the positive end of the terminal. In retro spec, the negative end of a battery goes to the negative end of the terminal.
What is the difference between a positive terminal and negative terminal of a battery?
The positive + terminal is slightly larger.
What is the positive terminal of a diode known as?
It is called the positive + terminal or post, just like you list. Electrons flow for the negative - to the + terminal contrary to popular belief.Another AnswerAs electrons flow through the external circuit from anode (negative terminal) to the cathode (positive terminal) , then the answer is 'cathode'.
When a dry cell is connected in a series the flow of electrons moves from the positive or negative terminal to the positive or negative terminal?
When a dry cell is connected in a series, the flow of electrons moves from the negative terminal to the positive terminal. Electrons are negatively charged particles and are attracted to the positive terminal while repelled by the negative terminal. This movement creates an electric current that flows through the circuit.
How many terminal does a battery have?
Two. The positive terminal, and the negative.
