Divide each side of that equation by 'voltage' :
Power/voltage = current
100 watts/110 volts = 10/11 Ampere = 0.9091 Amp (rounded)

Speed of sound is approx 740mph a police car with its siren sounding is approaching you at 80mph at what speed is the sound from the police siren approaching you?
The sound moves through the air at 740 mph, regardless of the speed of the source. The sound ofthe siren passes you at 740 mph.However, since the source is approaching you, more waves pass you each second than leavethe source each second. That's why the pitch of the sound from an approaching source soundshigher than its actual pitch.Also ... since the sound doesn't move away from the source any faster than 740 mph no matterhow fast the source is moving, that's why the pressure of the sound waves piles up in front ofthe source when the speed of the source approaches 740 mph, forming what's popularly calledthe "sound barrier".
How do you say 14000000000000000000?

Decibels in ear?
Never forget to tell the distance of the measuring microphone (at the place of your ear), from the the sound source because the closer you are to the sound source the louder it will be.The sound pressure level decreases by 6 decibels per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.The sound pressure decreases inversely as the distance increases with 1/r from the sound source.
Which of the following is not a source of problem cases?

How much is a 24kt 1gram gold bar worth?
A properly stamped 1 gram gold bar is useful as a long term, tangible investment. The value depends on the reputation of the bar's source, the current market value of gold, and the fineness of the gold bar (i.e., 0.9999 is more fine and pure than 0.9995). A hallmarked bar from Credit Suisse is worth more than a bar from some lesser known assayer. To find the minimum base value, get the current value for a troy ounce from a place like Kitco, and divide by 31.1034768. I hope this helps someone.
Examples of a circuit?
a circuit is a round wire that connects through a battery into a lightbulb
Why resistors are connected in series with the voltage source and in parallel with current source?
a voltage source has very less(negligible)resistance.thus is considered as a short.if connected in parallel to a resistor will draw all the current acting as a short.thus is always connected in series of a resistor.where as a current source has tremendous resistance(infinity).thus if connected in series will be conidered as an open branch and no current will flow through it other than the source current.
What is required for current to flow through an electrical current?
Potential Source connected across a Closed Circuit Path.
What happens to the current of R1 connected in series with R2 when it is also connected in parallel with R3?
The current, if connected to a voltage source that can supply the needed current to (R1+R2) R3, will be unchanged. If the source cannot supply the needed current, the terminal voltage will decrease, which will change the current flowing through R1 and R2.
What determines the actual magnitude and direction of current through voltage source?
The voltage itself will determine the direction of current (assuming there isn't another source pushing current through the source backwards); the amount of current will be determined by the thevenin equivalent resistance of the circuit connected to that source (the resistance "seen" by the source, which can be lumped into a single circuit element).
What is load current?
It is a the current drawn by the application that is connected to the power source
Wt is source current and sink current in a DC regulator?
The source current is that current which will leave the DC regulator and travel to the load circuit connected to it. The sink current is that current which may come from the load circuit and attempt to find a path through the ground through the regulator. Generally most regulators are designed to just source current to a load and are not setup to receive current back(sink it)
Will current flow in a higher resistance or in lower resistance if they are connected in parallel to a voltage source?
Current will always flow in both resistors, but the one with the lower resistance will have more current flow through it. The value of the current in each resistor is calculated by dividing the voltage of the source by the resistance of the individual resistor. As long as the capability of the power source isn't exceeded, the current through each resistor isn't affected by the presence of the other resistor. Said another way, if two resistors are connected in parallel across a source, neither one "cares" that the other resistor is connected across the source. The two resistors work independently.
Why is the current source connected in series only?
Current sources should not be connected in series. It's okay to connect them in parallel.
What is a circuit which will allow flowing current?
As long as an electrical power source is connected to itself with electrical conductors of some kind, then a current will flow through it. How much current will depend on the components used in the circuit.
Does electricity flow through wires?
Electric current flows through wires, but to transmit electric power you need two wires with a voltage between them, connected to a power source.
Will the voltage dropped across each resistor be same if two unequal resistors are connected in parallel?
yes ,they can be connected ,then they both will drive the current through that resistance ,the current through that resistance will be the sum of currents due to each individual source taking only one at a time (use superpositon theorem)
