When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
Why is it necessary to have a close circuit too have a complete transfer of energy?
Current can't pass through an open circuit .
What is a single route for electrical current called?
A single route for electrical current is called a branch circuit.
What happens if you add more loads to a series circuit?
When you have multiple loads in a series, the resistance of the loads is added together allowing very little current to flow through the circuit to power any of the loads, making for a low amperage circuit. If you have your loads in parellel, the resistance of the loads in the circuit is subtracted which allows more current to flow, making for a high amperage circuit.
What is a unit of measuring rate of electron flow in a circuit called?
Electron flow is known as 'current' the unit of current is an amp
If the resistance decreases in a circuit when the voltage remains constant the current will?
Current will increase
As the DC voltage applied to a circuit decreases what will the current do?
In a passive circuit, the current will decrease. In an active industrial circuit, it will usually decrease. In a theoretic manner - it is an unknown.
If voltage remains constant and resistance decreases current flow?
the current will increase because of a lower level of resistance , hence more current will flow- easily
What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
When current remains constant and resistance increases the voltage in the circuit will?
The physical equation governing voltage is V = IR, where V is voltage, I is current, and R is resistance. If V remains constant while R is increased, I or current must decrease. Increasing the resistance in a circuit is simply introducing a material that further resists or impedes the electron flow (current), thus current decreases.
Energy input remains constant and voltage remains the same in a circuit but current decreases why?
Power is voltage times current. If power and voltage remains the same, then current cannot decrease - it must also remain the same.The only viable explanation, assuming the question is valid, is that there is a parallel circuit, and one resistance increases while the other decreases, keeping the net resistance the same, but shifting the power from one branch to the other.Another answerNormally, if the voltage remains the same and the current decreases in a particular circuit, then the resistance of that circuit must be increasing and the total energy input must also reduce.If the total energy input remains constant (and yet the voltage remains the same) then some of the current being supplied by the source - and therefore also some of the energy - must be going to some other place outside the circuit in question, e.g. there could now be a ground fault...
How you increase current by keeping voltage constant?
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
As the resistance in a series circuit is decreased the amount of current in the circuit increases or decreases?
Increases the total resistance
In a series circuit each device that is added to the circuit decreases the what?
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.
What happens to the current flow in a circuit when a second component is added in series?
The total current decreases.According to the Ohm's law the current & the resistance are inversely proportional so when we put a load in series with the existing load, the resistance of the circuit increases therefor the current decreases.
In a series circuit each device that is added to the circuit decreases the?
Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.
