What else can I help you with?
Does current flow through a resistor, or does it flow across a resistor?
Current flows through a resistor, not across it.
Consider two identical resistors wired in series one behind the other If there is an electric current through the combination the current in the second resistor is?
Two resistors wired in series (no mater if they have the same resistor value or not) will always have the same amount of current flowing through them. Therefore, the current flowing through the second resistor will be equal to the current flowing through the first one. The current through every component in a series circuit is the same. The voltage across every component in a parallel circuit is the same.
What effect if any does connecting an ammeter in series with a resistor in a circuit have on the current though the resistor?
Connecting an ammeter in series with a resistor in a circuit will not affect the current through the resistor. The ammeter measures the current passing through it, so it becomes part of the circuit and simply measures the current flowing through the resistor without changing it.
How does a resistor slow down the flow of change in a circuit?
A resistor slows down the flow of current in a circuit by converting electrical energy into heat. This conversion of energy leads to a loss in voltage, limiting the speed at which the current can flow through the circuit. The resistance in the resistor opposes the flow of current, reducing its rate of change.
How does a resistor affect the flow of electricity in a circuit: does a resistor reduce voltage or current?
A resistor affects the flow of electricity in a circuit by reducing the current that flows through it. This reduction in current leads to a decrease in voltage across the resistor.
Does current flow through a resistor, or does it flow across a resistor?
Current flows through a resistor, not across it.
How does the potential difference in the resistor change as the current through it changes?
The potential difference accross the resistor changes mainly due to gradual increase accumulation of electrons in the lower potential region which will in turn affect the potential gradient as the current flows through the resistor
How current passes through resistor.?
What is the current running through resistor four?1 amps..!What is the current running through resistor one? 3 amps...!What is the current running through resistor three? 2amps..!What is the current running through resistor five? 3 amps..!What is the voltage drop running through resistor five? 45 volts...!What is the equivalent resistance through the parallel portion of the circuit? 6 ohmsAnswerA resistor is a conductor, albeit one with a higher resistance than a length of wire, so current passes through it without any problem. The magnitude of the current will, of course, be somewhat lower because of the additional resistance.
Is current is drop when it flowing through the resistor?
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
Why does a resistor heat up when an electric current flows through it?
Current moving through a resistor causes it to heat up because of the flowing electrons bumping into the atoms in the resistor.
What is a ballast resistor?
A ballast resistor is an electrical resistor whose resistance varies with the current passing through it, thus maintaining a constant current.
Consider two identical resistors wired in series one behind the other If there is an electric current through the combination the current in the second resistor is?
Two resistors wired in series (no mater if they have the same resistor value or not) will always have the same amount of current flowing through them. Therefore, the current flowing through the second resistor will be equal to the current flowing through the first one. The current through every component in a series circuit is the same. The voltage across every component in a parallel circuit is the same.
Does voltage flow across or through a resistor?
No. If a voltage is applied across a resistor, a current flows through it.
What effect if any does connecting an ammeter in series with a resistor in a circuit have on the current though the resistor?
Connecting an ammeter in series with a resistor in a circuit will not affect the current through the resistor. The ammeter measures the current passing through it, so it becomes part of the circuit and simply measures the current flowing through the resistor without changing it.
Does the change in the load resistor change the current in the arms of an unbalanced bridge?
No
What is the current drop across the resistor?
The correct question is what is the voltage drop across a resistor or the current flowing through the resistor using Ohm's Law where Voltage = Current x Resistance
How does a resistor slow down the flow of change in a circuit?
A resistor slows down the flow of current in a circuit by converting electrical energy into heat. This conversion of energy leads to a loss in voltage, limiting the speed at which the current can flow through the circuit.
