What else can I help you with?
What is a device that can control the current in a circuit?
A variable resistor can be used to control the current in a circuit by adjusting its resistance. By changing the resistance value, the amount of current flowing through the circuit can be regulated.
Can you increase current in a circuit without change in resistance and voltage?
no it is not possibleAnswerYes, by changing the voltage OR the resistance.
How does temperature affect current flow in electrical circuits?
Temperature can affect current flow in electrical circuits by changing the resistance of the materials in the circuit. As temperature increases, the resistance of the materials also increases, which can reduce the flow of current in the circuit. Conversely, as temperature decreases, the resistance decreases, allowing for more current to flow through 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.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the hypothesis of a rheostat?
The hypothesis of a rheostat is that by changing the resistance in a circuit using the rheostat, the current flowing through the circuit can be varied, thus regulating the output of the circuit.
When resistance is in a circuit what happens to the current?
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
What you will do to raise the temperature difference without changing the current?
To raise the temperature difference without changing the current, you can increase the resistance in the circuit. This can be done by adding additional resistors in series, using a material with higher resistance, or by adjusting the configuration of the circuit to increase the overall resistance. By increasing the resistance, the same current will produce a greater voltage drop across the resistors, resulting in a higher temperature difference.
Why doesn't current decrease in series resistance circuit though resistance opposes current?
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.
How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?
If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
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 happens to amps when you increase the resistance of a circuit?
When you increase the resistance in a circuit, the current (amps) in the circuit will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, so as resistance increases, current decreases.
