What is the result when voltage is multiplied by current?
The result when voltage is multiplied by current is power.
A high voltage combined with a low current will deliver less power than a moderate voltage combined with a moderate current.?
Correct. Power is determined by the product of voltage and current (P = V x I). A high voltage with low current has less overall power output compared to a moderate voltage with a moderate current due to the relationship between voltage, current, and power.
What is the main type of output energy in the curcuit?
The main type of output energy in a circuit is typically electrical energy, which can be in the form of voltage, current, or power. The output energy is often used to power devices or do work within the circuit.
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 remains constant in a transformer?
The turns ratio between the primary and secondary windings remains constant in a transformer, ensuring that the input voltage is transformed into the desired output voltage. The conservation of energy principle dictates that the total power input must equal the total power output, so the product of voltage and current in the primary winding will equal the product of voltage and current in the secondary winding.
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 a output voltage?
You can compare a power supply to a waterfall of energy. The high of the waterfall is the output voltage, and the quantity of water in the river is the current intensity. The power generate is a combination of the intensity and the voltage: P=UI (the effective power is the result of the multiplication of the voltage and the intensity). That explain why higher the voltage is, less intensity is needed to have the same power. It is the same in a waterfall, higher it is, less water you need to make a mill turning.
Why the rotor of an alternator at rated power dissipates more heat at a low power factor load?
In an alternator, the load current is supplied by the stator and the excitation is applied to the rotor. When the power factor is low (lagging), more excitation is required to maintain rated output voltage at rated current. More excitation is also required to maintain rated output voltage with increased output current. Increased excitation current means increased rotor losses that must be dissipated as heat. (akash)
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
Why is output dc higher than input ac?
Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).
What is the result when voltage is multiplied by current?
The result when voltage is multiplied by current is power.
Can you say which bridge rectifier voltage has the highest out put voltage?
A: NO the power output will be higher. Bridge rectifiers do not provide more voltage output it just add more power by rectifying both positive and negative voltage of the AC input
Can the amount of energy carried by a power line be increased by raising voltage?
The energy supplied by a power line is determined by its load, not by its voltage. For a given energy demand by its load, the higher the liine's voltage, the lower the resulting load current.
What do you mean by filtering output voltage?

Which voltages are supported by a Toshiba power supply?
The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.
Is the RMS value of the power output of a device running on a certain AC voltage equivalent to the power output of a similar device if it was running on the same voltage but it was DC instead of AC?
Yes.
How do you test power adaptor for Output volt regulation?
To test the output voltage regulation of a power adapter, you can use a multimeter set to measure DC voltage. Connect the multimeter probes to the positive and negative terminals of the output connector on the power adapter while it is plugged in and powered on. Compare the measured voltage with the rated voltage of the adapter to determine if it is within an acceptable range.
