Power (watts) is voltage times current.
What else can I help you with?
How are current and voltage related to the power supplied by the source?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
What is controlled voltage?
RPS is only the voltage& power controlled device. it can only used for set the input for our wish A device which can change its output according to the voltage supplied to it is called a voltage controlled device.ex. a voltage controlled current source,or a field effect transistor. In a voltage controlled current source the output current changes as the voltage supplied to it changes.
What does it mean to source current?
the source current is the current that flows from the power source.
How do you determine the power supplied to a motor with 1.0mA of current at 3.0V potential difference?
current times voltage equals watts or power
Where does some of your energy come from?
I am powered by electricity, which is supplied to me from a power source.
How many cables are supplied by a PC's power supply?
Usually only one, this is the main power source to the computer.
What is a power drawn from a power source?
A power drawn from a power source refers to the electrical energy consumed by a device or system to perform its intended function. This power is typically supplied by a source such as a battery, generator, or electrical grid, and is measured in watts.
How does an ac power source differ from a dc power source?
AC power sources are the adapter power sources. DC power sources are the direct power sources. DC stands for direct current, meaning it is a direct source of energy., and AC stands for alternating current, which means it is a secondary source of power.
How can a tuned RC circuit improve the power factor of an inductive motor circuit?
The RC circuit can reduce the phase shift between the voltage and current in the power line. The phase shift is caused by the inductance of the motor. The phase shift between the voltage and current in the power line causes problems due to the presence of so called imaginary current or power that does no work but must be supplied by the power source.
How can you differentiate DC and ac?
DC is direct current. It is characterized as a voltage or current that is constant or, more precisely, always in one direction. A battery is an example of a DC source. AC is alternating current. It is characterized as a voltage or current that is alternating, i.e. changing direction at some frequency such as 50Hz or 60Hz. The power supplied to your home from the public power utility is an example of an AC source. ac is attractive in nature while dc is repulsive .
What is required for a circuit to have a current?
a power source
How could you calculate the resistance of a circuit?
A variety of techniques can be used. Node-Voltage and Mesh-current (or Loop-current) methods, for example. See related link for examples. If there is a single voltage source in the model, then find the current supplied, and Resistance = Voltage/Current. {R = V/I} You could simulate/ model the circuit on a computer then apply the power profile and a current value will be calculated. Or if you have the circuit working, Place an amp meter into the circuit and measure the current. V/i = resistance.
