If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
What else can I help you with?
How is current distributed in a series circuit?
In a series circuit, all components gets the same amount of current passing through them.
In a parallel ac circuit is the current additive?
Yes In parallel circuit , current entering into the circuit will be divided intodifferent paths ( resistances) . Amount of current flow depends upon the magnitude of resistance applied in the circuit. Total current after passing through the circuit will be the sum of all current through each resistance.
An increase in resistance in a circuit will cause?
In a simple circuit, lowering the voltage will not cause the resistance to do anything. Lowering the voltage will, however, cause the current to also lower.This ignores temperature coefficient. If there is substantial power involved, a typical bulb, for instance, will grow cooler and its resistance will decrease when you lower the voltage, but that is usually a small effect.
If voltage changes in a ac circuit what happens to current?
Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.
Will the impedance in a series RL circuit increase as the frequency decreases?
When the frequency of Parallel RL Circuit Increases,XL increases which causes IL (current through inductor) decreases. Decrease in IL causes It (It=Il+Ir) to decrease,which means by relation IT=Vs/Zt ,the Zt (Total Impedance) Increases.
How does added resistance affect the brightness of the bulb?
Added resistance in a circuit will decrease the current flowing through the circuit, resulting in a decrease in the brightness of the bulb. This is because the bulb's brightness is directly proportional to the current passing through it. More resistance means less current, which leads to reduced brightness.
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 is current distributed in a series circuit?
In a series circuit, all components gets the same amount of current passing through them.
In a parallel ac circuit is the current additive?
Yes In parallel circuit , current entering into the circuit will be divided intodifferent paths ( resistances) .

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.
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 is the name of a device that can be used to control the amount of current?
A resister limits the amount of current passing through a circuit.
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
What is a break in an electrical circuit called?
A break in an electric circuit is called an open circuit. Electric current will not flow through an open circuit.
What do amps do in a series circuit?
In a series circuit, the current (amps) is constant throughout the circuit. This means that the same amount of current flows through each component connected in series. The current is not divided or reduced as it travels through the circuit.
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.
When reversed biased a diode acts like an open circuit?
The key function of a diode is to control the direction of the flow of current. Current passing through a diode can only go one way, which is called forward biased. In this setup, current is continuous hence the circuit is closed. When there is no current passing through, there will be no flow, and this is called reversed biased. In such a case, current is not continuous, hence it is called open circuit.
