What else can I help you with?
Is the increase in voltage causes a greater electric resistance in a circuit?
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
True or false if the voltage and resistance of a circuit stay constant the amperage can never change?
The equation for the three values in the question will give the definite answer.Amperage (I) is equal to the voltage (E) divided by the resistance (R).I= E / R So as you can see the answer is True.Example: 10 Volts and 50 Ohms in a circuit will have a current of .2 Amperes flowing through it. 10 / 50 = .2You can also rearrange the equation to find the other two:E= R * ER= E / I
What does a thermister do and how does it function in a circuit?
A thermistor is a type of resistor that changes its resistance with temperature. In a circuit, a thermistor is used to measure temperature by detecting the change in its resistance. When the temperature changes, the resistance of the thermistor changes, which can be measured and used to determine the temperature in the circuit.
Does potential difference change with change in resistance?
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
How do you increase amperage without changing voltage or resistance?
You cannot increase amperage without changing voltage or resistance. Ohm's law states that voltage is current times resistance. You cannot change one alone. Not even changing frequency in a capacitive or inductive circuit will do this, because changing frequency represents a change in reactance, which is effectively a change in resistance.
Will the current of circuit change on changing the ammeter resistance?
The accuracy of ammeter changes as the resistance is increased or decreased.AnswerThe simple answer is yes, it will change. However, whether it will be a perceptible change is another question. Ammeters are designed to cause the minimum change to the actual circuit current when they are inserted into a circuit.
What is the main function of resistances in fire alarm circuit?
Heat changes the resistance of a circuit. The change is detected by the system, and activates the alarm.
When the resistance in an electrical circuit increases and the voltage does not change the current flowing in the circuit?
Here is the formula you use. I = E/R. I = amperage, E = volts, R = resistance in ohms.
How do you change the ratio of a current to voltage?
Change the resistance in the circuit
What is the relation between amperage and capacitance?
The relationship between amperage and capacitance is indirect. Capacitance stores and releases electrical energy, affecting the flow of current in a circuit. Higher capacitance can lead to slower changes in current (i.e., lower frequency), while lower capacitance can result in faster changes in current.
What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
What is role rheostat?
it is a device which is used to change the resistance of circuit.
