How do you provide some method of voltage division to meet equipment used?
Voltage division is a very complicated way to change the voltage supplied to a piece of equipment. You need to install a transformer, if the difference is significant, and transformers should only be installed by qualified professionals.
What transports electricity to your home?
Electricity is transported from the places where it is made to the points of use by what we call the power grid. It's all those wires you see up on those tall poles and those big tall towers. It's done with wires.
Why should you be thankful for electricity?
Electricity has many uses. We use electricity to switch on the lights in our homes, switch on the stove and oven to cook and bake, the washing machine to wash our clothes, as well as for many other things. Electricity is also used by machines in factories to make many products that we use everyday. We can see that electricity has many uses, therefore we must be thankful for the electricity that is supplied to us.
Can you plug a 110V appliance into a 115V outlet?
120 Volts and 115 Volts refer to the same thing in the US. Residential electricity is provided at 120 Volts from the utility. High current devices such as motors are often rated at less than the supplied voltage (such as 115 Volts) because it is expected that there is a small amount of voltage drop in the circuit feeding them. The National Electric Code allows a 5% drop in voltage from the electric service so a 5 Volt drop from 120 Volts is OK.
How can you work safely with electricity at home?
The safest way to work with electricity in any place is to de-energize the circuit and test with a meter or hot stick. We prefer meters because hot sticks are very unreliable and sometimes to sensitive. Always test a meter or hot stick on a known live circuit before relying on it. Even if you are 100% positive the circuit is de-energize you should pretend its not and respect it. Electricity can kill you, regardless of the voltage or amps. Any voltage or amperage can kill! If your not a pro, call one!
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
What system voltage should be used for a house that needs a power of 12KW?
There is no choice of what voltage that you are supplied for your home. You are governed by what the utility company in your area supplies.
Why you should use insulators?
They protect you from a shocking reminder of how powerful high voltage electricity is
If the fed wants to increase the money supply it should?
If the Fed wants to increase the money supply, they should buy the government bonds. The actions that can be used by the Fed to increase the money supplied is called the monetary policy.
When a battery runs out does the battery voltage increase decrease or stay the same?
It should decrease
What is amount of voltage supplied at night?
In theory, voltage should be the same around the clock. In practice you may get a tad higher voltage at nights, as there's less load on the system. With most people asleep, there aren't as many machines running.
Technician A says that the current draw should decrease as the voltage decreasestechnician B says that the current should increase as the voltage decreases Which technician is right?
Both technicians are right, and both technicians are wrong, because not enough information is present in the question, nor in their statements. Given constant impedance, current should decrease as voltage decreases, while given constant power, current should increase as voltage decreases.
An increase in temperature will the attenuation of a cable?
Basically we should also keep in mind knowledge about voltage and current. If we keep voltage constant then by increase in temperature also increase the attenuation, if we keep current constant then attenuation drops by increasing temperature.
What must you match when purchasing a power supply?
The equipments power requirements, and the mains voltage. The output of the power supply must be able to deliver the correct voltage to the equipment, at the appropriate wattage. Additionally, it should be capable of operating on the supplied mains voltage and wattage.
How do you provide some method of voltage division to meet equipment used?
Voltage division is a very complicated way to change the voltage supplied to a piece of equipment. You need to install a transformer, if the difference is significant, and transformers should only be installed by qualified professionals.
What would happen if the resistance in a circuit remained the same and the voltage decreased?
A well designed circuit should be able to operate over a range of voltages, not just at one voltage. Especially a circuit which is intended to be powered by a battery. As the battery starts to get used up, and the voltage drops, you want the circuit to operate as planned.
What is the acceptable percentage of voltage acceptable variance that most appliances will accept?
When doing voltage drop calculations the voltage to the connected devices should not drop below 3 % of the supplied voltage. <<>> "Most" appliances? that a tough one there is no standard. A few percent is no trouble, different appliances have different tolerances: no generalizations are possible.
