What else can I help you with?
Does the resistors current changes if the voltage across a fixed resistors is cut in half?
If the voltage across a resistor or resistors is halved, then the resulting current will also fall by half.
The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
Do resistors reduce current or voltage in an electrical circuit?
Resistors reduce the flow of current in an electrical circuit, which in turn affects the voltage across the circuit.
What is true of a series circuit that has two resistors?
Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.
Why do electrons have different amounts of energy at different points of the circuit?
Electrons have different amounts of energy at different points in the circuit due to the presence of components like resistors, capacitors, and inductors which can absorb or release energy as electrons move through them. The voltage across different components in the circuit determines how much energy the electrons have at that particular point.
What happen to the voltage across each resistor when all of the resistors are doubled?
Nothing. But the current is halved.
Which device contains capacitors which store enough electricity in them to cause injury and possible death to a technician and you are not to service?
High-voltage power supplies can retain the voltage in the capacitors after being switched off. However good design has resistors connected permanently across the capacitors to discharge them in 5-10 seconds after switch-off. Obviously the resistors absorb power so their value in ohms is a compromise, not usually a difficult one.
Why are discharge resistors connected across large industrial capacitors?
A: Discharge or bleeder resistance are there for only one reason to bleed the charge when the power if off and unless there is a paths for those capacitors to be discharged the power stored there can be lethal to humans or detrimental to the circuit
Why load resister is conected across the circuits?
Load resistors are connected across the circuit to limit the current flowing through the load.
Resistors connected in a single path is called?
The resistors connected in single path are called series resistances or resistances in series.The current across both the resistors is same while the potential differences are different.
How are the plus and minus voltage signs determined for resistors?
Resistors have no polarity. The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).
What causes a voltage drop in an electrical circuit?
A voltage drop in an electrical circuit is caused by resistance in the circuit components, such as wires, resistors, or other devices. This resistance reduces the flow of current and results in a decrease in voltage across the circuit.
