Reducing the current to a circuit causes a higher resistance -- assuming constant Volts. Also, reducing the current to a circuit causes lower Volts -- assuming constant resistance.
AnswerAltering the current has absolutely no effect on a circuit's resistance. Reducing the current will reduce line losses (I2R) and reduce the voltage drop along a conductor.
What else can I help you with?
Why reducing current in circuit?
The current in a circuit is reduced to prevent the circuit from over load.
What causes a current in an electric circuit?
Voltage causes current to flow in an electric circuit.
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
When the wires are connected to the terminals of the battery what causes electric current in a circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
What causes an elecrtic current to flow in a circuit?
The movement of electron towards the high potential causes electric current to flow in a circuit.
How do resistors limit the flow of current in a circuit?
Resistors limit the flow of current in a circuit by impeding the movement of electrons, causing a drop in voltage and reducing the overall current passing through the circuit.
What causes a short circuits?
-circuit damage -overheating -fire or explosion causes a short circuit.
How do we decrease the brightness of a bulb?
If the bulb is of the incandescent variety, then reducing the current in the circuit will do this.
Circuit breakers are used for what?
Circuit breakers prevent excessive current from flowing in the circuit by "tripping" when the current exceeds the circuit breaker rating. This causes the current to be cut off, and is used to protect the wiring as well as the appliances.
How do resistors affect the change in current flowing through a circuit?
Resistors in a circuit reduce the flow of current by impeding the movement of electrons. This causes a decrease in the overall current flowing through the circuit.
How does a resistor affect the flow of current in an electrical circuit?
A resistor restricts the flow of current in an electrical circuit by resisting the flow of electrons. This causes a decrease in the amount of current that can pass through the circuit.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
