What is instantaneous power mean?
The product of the instantaneous voltage and the instantaneous current for a circuit or component.
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)
Does a transformer boost electric energy?
The transformer doesn't "boost" energy. If the voltage on the output side is higher than the voltage on the input side, then the current is lower. The power (energy every second) on either side is the product of (voltage) times (current), and that product is the same on both sides of the transformer.
Power equals voltage times what?
In DC, power equals voltage x current. In AC, power equals voltage x current x power factor. The power factor is an adimensional constant, and in common circuits it is often close to 1.
How can you calculate the current an appliance can use?
current=watts(power)/voltage
Is the power is product of voltage and current?
yes
Is the product of voltage and current?
power in watts
Which component links power and voltage?
current is the other factor. power (wattage) is the product of current (amps) and voltage
How can power be calculated from current and voltage?
Power is the product of voltage and current -in other words, mutliply the two together.
What is the product of current and voltage?
power in watts
What is the relationship between voltage power and current?
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
What is a volt-ampere the product of?
A volt - ampere is the unit for the product of voltage and current. This is power. Power = voltage x current. The unit of power is more usually called the watt. Volts x amps = watts.
Which actually does work in circuit voltage or current?
Power (energy per time unit) actually depends on both. In a DC circuit, it is the product of voltage and current. In an AC circuit, it is the product of voltage x current x (power factor). The power factor is often close to 1.
What increases when current increases?
If current increases, then voltage also has to increase, assuming that resistance stay relatively the same. Power will also increase. Since power is the product of voltage and current, then the power increase would be the square of the voltage or current change.
What is meaning of apparent power in transformer?
Apparent power is the product of voltage and current in an a.c. system, and is expressed in volt amperes. The rated apparent power of a transformer is the product of its rated secondary current and rated secondary voltage.
What is the power dissipated by a resistor that has 5 amps flowing through it with 120 volts applied?
The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
