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 is added to a circuit to make the current smaller?

The reduction of voltage or the increase of resistance will reduce the current in a circuit.


In a series circuit each device that is added to 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.


What changes occur in the total resistance of a circuit as additional resistances are added in parallel?

The total resistance of the circuit increases. hence the new resistance after adding the resistance will be new resistance = old resistance + added Resistance There is a small mistake in the question. The second word is 'changes' not 'charges'


What will happen if a second bulb is added to a parallel circuit?

-- The voltage doesn't change. -- If the second light bulb is identical to the first, then the total resistance drops by half. -- If they're not identical, then we have to know the details of both before we can calculate their combined effective resistance.

When you add resistors that are in a series to a ciruit?

You raise the total resistance by that amount if added in series to a circuit. If you add them in parallel to a circuit then that total resistance will be less than the total of the added circuit.


How is resistance added in a series circuit?

Resistance in a series circuit is added by simply connecting resistors end-to-end. This results in the total resistance being the sum of the individual resistances. The current passing through each resistor in a series circuit remains the same.

When more light bulbs are added in parallel to a circuit what happens to the total resistance of the circuit?

When more light bulbs are added in parallel to a circuit, the total resistance of the circuit decreases. This is because in a parallel circuit, the reciprocal of the total resistance is equal to the sum of the reciprocals of the individual resistances. More paths for current to flow mean less overall resistance in the circuit.


Why does the total circuit resistance decreases when more devices are added to a parallel circuit?

Does it? See Related Links

Is resistance in a series circuit equal to the largest resistor in the series?

No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!


Does the current split in parallel circuits affect the overall resistance in the circuit?

Yes, the current split in parallel circuits does affect the overall resistance in the circuit. In a parallel circuit, the total resistance decreases as more branches are added because the current has multiple paths to flow through, reducing the overall resistance.


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.


If the resistance in the circuit is increased what will happen to the current and voltage?

* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.
