What converts light signals into digitally formatted electrical signals?
To convert light signals into digitally formatted electrical signals requires a device called a camera. Also, an optical fiber digital converter in the course of fiber optics. For electrical power transmission, photovoltaic cells convert light into power.
What components are placed in an electrical circuit to control the amount of resistance in circuit?
resistors, variable potentiometers
Meaning of 60watt's in 60watt's bulb?
60 Watts is the amount of electrical power the bulb uses when it is switched on.
What would one use a strain gauge for?
Like the name suggests, a strain gauge is a device used to measure the strain of an object. The devices electrical resistance varies in proportion to the amount of strain on the device.
Can a better ground lower electric bill '?
No, the only way that the electric bill can be reduced is to reduce the amount of electrical energy used.
How electrical devices in homes give off small amount of heat true or false?
True that electrical devices generate some amount of heat.
What are photoelectric cells?
Photoelectric cells are devices that generate electrical output that is dependent on the amount of illumination. They are used in various mechanical devices to set off alarms or open doors.
Why don't you power your homes with fruity batteries?
-- The electrical devices that we've become accustomed to using in our homes need much more power than any reasonable amount of fruit can deliver. -- The electrical devices that we've become accustomed to using in our homes operate on AC, whereas fruit delivers DC. -- When you take into account the energy and other resources required to plant, grow, harvest, distribute, install, operate, and maintain fruit, it isn't that much of a bargain compared to the current methods of mass producing electrical energy. -- The whole notion of turning food into fuel for cars, TVs and washing machines is demented.
Will a subwoofer drain your car battery?
All electrical devices create at least some amount of drain on your car's battery. Although the amount will vary by device, a properly wired system will charge via the car's alternator with no adverse effects.
What instrument is used to vary electrical resistance in a device?
Virtually all electrical devices (actually, all except for superconducting devices) have resistance. There is one type of electrical device that is found in almost every electronic circuit ever invented. It is used wherever the designer needs a specific amount of resistance in the circuit. I'd hate to spoil your fun by simply telling you its name. Think of all of the different names of electrical devices that your teacher has told you about. (or look in the index of your text book if you're in a hurry) Is there one that comes to mind when you think of RESISTance?
How to determine the amount of watts needed to operate a household?
You can connect a watt meter to the circuit or it can be done by calculation. By calculation use this formula, Watts = Amps x Volts.
A kitchen blender transforms electrical energy into mechanical energy Why is the amount of mechanical energy produced less than the amount of electrical energy used?
Losses are due to inefficencies of the motor, and friction on moving parts.
Can you insert the plug which says ac 100-127 on a 220 outlet?
No, the rating on electrical devices is the maximum amount of voltage that is legally allowed on the device. This is usually established by the physical clearances between electrical potentials. The higher the voltage, the more space between live electrical components. This is controlled by using different pin configurations of plugs and receptacles for different voltages and amperages.
How can you reduce maximum demand without reducing the amount of electrical equipment installed?
You can identify which appliances use the most power and then ensure that they are not used at the same time. For example don't operate a cooker at the same time as taking a power-shower.
What term describes the amount of electrical energy used in a certain amount of time?
kilowatthours
What terms describe the amount of electrical energy used in a certain amount of time?
