Does increasing the resistance increase the electric current?
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
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.
What change occurred to the total resistance of the circuit when the extra globe was added?
When an extra globe is added to a circuit, the total resistance depends on how the globes are connected. If they are connected in series, the total resistance increases because the resistances add together. If they are connected in parallel, the total resistance decreases, as the overall resistance is reduced by the additional path for current flow. Therefore, the change in total resistance depends on the configuration of the globes in the circuit.
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.
When a second identical bulb is added in series to a circuit with a single bulb the resistance of the circuit?
When a second identical bulb is added in series to a circuit with a single bulb, the total resistance of the circuit increases. This is because the resistance of each bulb adds together, resulting in a total resistance that is double that of a single bulb. Consequently, the overall current flowing through the circuit decreases, as per Ohm's Law (V = IR), assuming the voltage source remains constant.
What happens to the power of an electric circuit of the resistance is decreased?
if the resistance is decreased and the current stays the same, then the power decreases.
When an ammeter is connected to measure current circuit current will decrease sightly because R total decreases after the meter is inserted?
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
When resistance decreases what happens to current?
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
When one load is removed from a parallel circuit the total resistance decreases?
No, the total resistance increases.
What happens when a part of a parallel circuit is disconnected?
current decreases and resistance increases
What happens to the current in circuit as the resistance increases?
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.

What is the relationship between voltage and resistance in an electrical circuit?
In an electrical circuit, the relationship between voltage and resistance is described by Ohm's Law. This law states that the voltage across a circuit is directly proportional to the resistance in the circuit. In other words, as resistance increases, the voltage required to maintain the same current also increases. Conversely, if resistance decreases, the voltage required to maintain the same current decreases.
How does temperature affect current flow in electrical circuits?
Temperature can affect current flow in electrical circuits by changing the resistance of the materials in the circuit. As temperature increases, the resistance of the materials also increases, which can reduce the flow of current in the circuit. Conversely, as temperature decreases, the resistance decreases, allowing for more current to flow through the circuit.
What effect does decreased resistance have on a circuit?
resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.
What is the relationship between current and resistance in a circuit when the voltage is kept constant?
In a circuit with constant voltage, the relationship between current and resistance is inversely proportional. This means that as resistance increases, the current flowing through the circuit decreases, and vice versa.
