Power Dissipation
A: is not current or voltage but rather the product that is of concern
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.
Voltage is the product of current times resistance, V=IR, I is Current and R is resistance. ANSWER: It is a simple ratio of 1:1:1
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
power in watts
The current in the secondary when the voltage is twice the primary will be one half of the primary. The current in the primary when the voltage is twice the secondary will be twice the secondary.
The terminal voltage is equal to the supply voltage and there is zero current.
yes
power in watts
Voltage
current is the other factor. power (wattage) is the product of current (amps) and voltage
Power is the product of voltage and current -in other words, mutliply the two together.
Because it's the product of the transformer's rated secondary voltage and its rated secondary current. The product of voltage and current, in a.c., is the volt ampere.Incidentally, it's 'kV.A', not 'kva'.
A: is not current or voltage but rather the product that is of concern
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.
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.
There is no difference of magnitude to be considered the end product is the same.
