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.
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 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.
What happens to the ammeter reading when a lamp is added to a circuit which contains two cells and a lamp in series?
Assuming the new lamp is in series, the ammeter reading falls because the total resistance has increased. By how much depends on how the lamp resistance depends on voltage. If the lamp is added in parallel to the first, then the ammeter reading doubles.
Why external resistances are added to armature circuit in a dc motor?
extra resistance is added in order to decrease starting current and improve starting torque
What happens when one bulb is added to a series circuit?
The resistance is increased, the voltage across each bulb is decreased and the current through the circuit is reduced.
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.
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.
What happens when more branches are added to a parallel circuit?
Adding more branches to a parallel circuit decreases the overall resistance of the circuit. This leads to an increase in the total current flowing through the circuit as each branch provides an additional pathway for the current to flow. This results in a decrease in the total resistance and an increase in the overall current of the 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.
What happens to the resistance in a parallel circuit when more light bulb is added?
When more light bulbs are added to a parallel circuit, the total resistance decreases because each additional bulb provides an additional pathway for current to flow. This results in an increase in the overall current flowing through the circuit, as well as an increase in the total power consumed by the circuit.
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 happens if you add more loads to a series circuit?
If you add more loads to a series circuit, the overall resistance in the circuit increases, which decreases the overall current flowing through the circuit. This can result in a decrease in the brightness of light bulbs or a decrease in the speed of motors connected in the circuit.
Why does the total circuit resistance decreases when more devices are added to a parallel circuit?

What happens if you add more loads to a series?
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 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.
