β 14y agoThe resistance of the new bulb is likely higher than the previous bulb. Increasing resistance in a series circuit decreases current flow. When resistance increases, less current can flow through the circuit, resulting in a decrease in current.
Electric current can be started by closing a circuit, allowing the flow of electrons. This can be done by pressing a switch to complete the circuit. To stop the flow of electric current, the circuit needs to be opened, typically by opening the switch, which interrupts the flow of electrons.
The current in a circuit is typically measured in amperes (A). To describe how much the current is slowed in a circuit using a narrow wire, you could specify the reduction in amperes (A) or use units like percentage (%) or ratio to convey the change in current flow.
You can change current by altering potential difference or resistance... But assuming the voltage is constant, the resistance of the circuit restricts the flow of electrical current.
A simple method for altering the magnetic flux would be to change the amount of current flowing in the coil or circuit. Generally speaking, more current, more magnetic flux, and vice versa.
90 degrees. In an AC circuit with a pure capacitance, the current leads the voltage by 90 degrees. This is because the current in a capacitor is proportional to the rate of change of voltage across it, leading to this phase relationship.
In a series circuit, adding more light bulbs increases the resistance in the circuit. As a result, the total current in the circuit decreases because the voltage remains constant. The current is shared among the components in a series circuit, so adding more bulbs decreases the current that flows through each bulb.
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.
-- In a series circuit, no matter where you install the ammeter, it will always read the same current. -- In a parallel circuit, the ammeter may read a different current when it's moved to a different parallel branch.
A: In series circuit the current remains the same no matter how many components are in series. just the voltage will change to reflect different voltage drops for each.
the current value at any part of the circuit is dependent upon the circuit conditions and not the ammeter. The meter will simply allow you to read those currents, whatever they may be.
Change the resistance in the circuit
Here is the formula you use. I = E/R. I = amperage, E = volts, R = resistance in ohms.
non-linear circuit
A: In a series circuit the current remains the same for each components only the voltage across each component will change and only if the components are of different value.
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
DC current has no effect on the inductor(can be considered as a short circuit) as the current does not change in a DC supply voltage this one just produces a magnetic field which remains constant , as the magnetic field is not varying no emf is induced in the circuit , so literally it has no effect on the circuit when the supply is of DC voltage.when an alternating current is set up in a circuit , the Alternating current brings a magnetic field in the inductor which is variable (since the current is varying...) this variable magnetic field induces an emf in the circuit (back emf) which opposes the cause that is producing the change (lenz's law)explanation consider a circuit with an inductor connected to an AC voltageduring the positive half cycle when the voltage increases the current also increases in the circuit [take the current direction as clockwise] this causes a variable increasing magnetic field in the inductor , this magnetic field in turn induces current in the circuit which is opposing the increase in the current flow from the original source, the inverse happen during the decreasing half of the half of the positive cycle , here the induced current adds up with the decreasing current opposing the cause that produced this back current (cause :- decrease in current changes the magnetic field so the induced current is produced ..... it is opposing the change because :- the induced current either decreases the increasing current or increases the decreasing current )
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.
