What is the relationship between power, current, and voltage in an electrical circuit?
In an electrical circuit, power is the product of current (the flow of electric charge) and voltage (the force that drives the current). The relationship between power, current, and voltage is described by the equation P I x V, where P is power, I is current, and V is voltage. This equation shows that power increases when either current or voltage increases in a circuit.
What happens if the track of the current is broken in a series circuit?
If the track of the current is broken in a series circuit, the circuit will be interrupted and no current will flow. The components in the circuit will not receive any power and will not function until the circuit is repaired.
What is the relationship between power and voltage in an electrical circuit?
In an electrical circuit, power is directly proportional to voltage. This means that as voltage increases, power also increases, and vice versa. The relationship between power and voltage can be mathematically expressed as P V x I, where P is power, V is voltage, and I is current.
What happens when the circuit is closed?
When a circuit is closed, it forms a complete path for the flow of electric current from the power source (such as a battery) through the circuit components (resistors, capacitors, etc.) and back to the power source. This allows electrical energy to be transferred and used to power devices connected to the circuit.
What is electrical fore proportional to?
In a direct current (DC) circuit, electrical power is proportional to both voltage and current according to the equation P = V * I, where P is power, V is voltage, and I is current. This relationship dictates that as either voltage or current increases, electrical power will also increase.

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 happens if the track of the current is broken in a series circuit?
If the track of the current is broken in a series circuit, the circuit will be interrupted and no current will flow. The components in the circuit will not receive any power and will not function until the circuit is repaired.
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.
