According to the different coefficient of resistance change, thermistors are divided into two types: positive temperature coefficient thermistor (PTC), whose resistance value increases with increasing temperature, and negative temperature coefficient thermistor Resistance (NTC), whose resistance value decreases with increasing temperature.

The function of thermistor is temperature compensation and temperature control. After the current passes through the element, the temperature rises, that is, the temperature of the heating element rises. When the rated temperature is exceeded, the resistance increases, thereby limiting the current increase, so the decrease of the current causes the temperature of the element to decrease, and the decrease of the resistance value increases the circuit current. The element temperature rises and repeats itself, so it can keep the temperature within a specific range.

∙ 12y agoThe resistance of a thermistor decreases when the temperature increases. So more current can pass when the thermistor has a high temperature.

What is the affect of a series circuit on current?
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .
How can an ammeter be connected in a circuit and not effect the flow of current?
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
State three things which can affect the voltage in a circuit?
Ohms Law says that Voltage = Current * Ohms, so the twothings that can affect the voltage in a circuit are Current and Ohms. If have a non resistive impedance, i.e. a capacitor or inductor forming a reactance, then frequency can also affect the voltage but, mathematicaly, reactance is a frequency domain form of impedance, so my answer stands - Current and Ohms.
How might ambient temperature may affect the resistance values you would measure in a circuit?
Ambient temperature might affect the readings of the resistance value you would measure because the resistance of some materials changes with the temperature.
What causes resistance to increase or decrease?
Voltage, if voltage is increased resistance in the circuit increasesAnswerResistance is determined by the length, cross-sectional area, and resistivity of a conductor. Resistivity is, in turn, affected by temperature -so temperature indirectly affects resistance.These are the only factors that affect resistance. Voltage and current have no direct effect whatsoever on resistance. Current can affect resistance indirectly if it causes the conductor's temperature to increase.For AC circuits, 'skin effect', due to frequency, causes the current to flow towards the surface of a conductor which acts to reduce the effective cross-sectional area of that conductor. So, frequency can also indirectly affect resistance.
Reducing voltage in a circuit does not affect resistance?
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
Do additional resistors affect current in a series circuit?
Yes, additional resistors affect current in a series circuit by increasing the total resistance, which decreases the total current.
What is the affect of a series circuit on current?
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .
How do resistors affect a circuit?
It reduces the current. As the current travels through the resitors it has some current that is left in the resistor. And
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
How can an ammeter be connected in a circuit and not effect the flow of current?
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
Does electric current remain constant in a circuit?
No it depends on voltage and circuit resistance and other physical parameter which affect the properties of component used in circuitry like - temperature pressure humidity light(in light sensitive circuit- LDR photo diode,photo transistor,) and other.
How can a broken wire affect a series circuit differently than a parallel circuit?
In a series circuit, all the current passes through the one circuit. Any break will totally remove power from all of the circuit.Parallel circuits have more than one branch where the current can flow. A broken wire will only affect one part, the rest of the circuit will still pass current.In a series circuit, all the current passes through the one circuit. Any break will totally remove power from all of the circuit.Parallel circuits have more than one branch where the current can flow.

Why is it capacitance does not affect current in a Direct Current circuit?
Capacitors resist a change in voltage, proportional to current and inversely proportional to capacitance. In a DC circuit, the voltage is not changing. Therefore, after equilibrium is reached, there is no current flowing through the capacitor.
What factors affect the inductive reactance of a coil in a A C circuit?
Current Flow I believe.
How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
