What happens to the power in a circuit as the current increases?

P=VI
If current (I) increases then P will increase proportionally. That is, assuming that voltage (V) remains constant.
If voltage decreases and current increases or vice versa, proportionally then P will remain the same.

What else increases as energy carried by a current increases?
The amount of electric energy that is converted into thermal energy increases as the resistance of wire increases. As the resistance in the current increases, the current in the circuit decreases.
If you multiply the voltage in a circuit by the current what are you going to get for your answer?
Voltage x current = power (watts)
Why does a circuit stop working when you remove the battery?
The battery is the power source of the circuit. It supplies current to the circuit and the circuit is simply a path for the current to follow. When you remove the current (battery), the path still exists but there is no current going through it.
How do you find power in a circuit?
P=IV Power=current x voltage
What is the current in a circuit that has a resistance of 30 ohms and a power of 2 watts?
Use the formula: P=IR (power = current x resistance).
What happens the power consumption of a circuit as its resistance increases?
😉
What happens to the voltage if the current increases?
Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.
Current travels from a power plant to a transformer that increases voltage through a what?
circuit
As the voltage applied to a circuit increases the current and the also increase?
answer is actually voltage
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.
In a circuit with resistive and inductive load what happens to the power factor as the resistive load increases?
The PF will increase
What else increases as energy carried by a current increases?
The amount of electric energy that is converted into thermal energy increases as the resistance of wire increases. As the resistance in the current increases, the current in the circuit decreases.
In a shorted circuit what happens to the temperature of the wires?
In a shorted circuit, the temperature of the wires increases. This is because the wires are not perfect conductors - they have resistance - so the large fault current that flows generates a voltage across the wires, which then generates power, generating heat.
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.
What happens to voltage when current is increased?
current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.
What is the flow of an electrical current in a circuit outside the power source?
Usually a circuit is connected to a power source, which could be a battery or an outlet. When this happens current flows through the circuit. The power supply raises electrical charges through the required potential difference, and then in the circuit the charges flow down the potential gradient giving up their energy.
What happens if there is a break in a serious circuit?
A break in an electrical circuit will cause the circuit's load to stop operating.
