Technically speaking, voltage does not run through anything, current does.

Voltage is the difference in electric potential energy per unit charge between two points. A voltage applied to a load (e.g. appliance) in a closed circuit will cause current to flow and make the load "work". If you apply a different voltage to something other than what it was designed to run on, it will most often not work or burn up.

The amount of current that will flow through a device operating from a fixed voltage (like that coming out of the wall in your house) is directly proportional to the resistance. Lower resistance = higher current.

Does the voltage that runs through different appliances vary according to the resistance of the appliances?

No, it is the current (amperes) that vary according to the resistance.


Does the voltage that runs through different appliances vary according to the resistance of appliances?

Voltage does not 'run through' anything! Voltage is another word for potential difference which exists across a circuit's load. You can think of voltage as being equivalent to 'pressure' -pressure does not 'run through' anything, either, it is applied 'across' two points in a hydraulic or pneumatic system.So, if the appliances are connected in parallel (usually the case), then the potential difference across each appliance will be the same.


How did Georg Ohm study the resistances of different materials?

Georg Ohm studied the resistances of different materials by conducting extensive experiments with various substances to measure their resistance to electric current. He developed Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance. This law laid the foundation for understanding and quantifying electrical resistance in different materials.


Do individual lines in a parallel circuit have different currents flowing through them?

They can. The current in each "line" (correctly, *branch*) depends on (i) the applied voltage and (ii) the individual resistance in each branch. If the branch resistances are different, the branch currents will be different. Ohm's Law will let you calculate the individual currents.


Why is it that in series connection the light of the bulb is different to one another?

In a series connection, the same current flows through each component. When bulbs are connected in series, the total voltage is divided across each bulb based on its resistance. As a result, bulbs with different resistances will have different brightness levels.


When lg appliances are known to be a smart appliance what does that mean?

LG appliances are known to be smart appliances because they feature a wifi connection. They can connect through a 'smart network' which save time and energy.

What is a seiries circuit?

Series CircuitWe say Resistances are in series if the same current flows through all Resistances. A circuit containing of only series resistances is called a series circuit. A series circuit is a circuit that has the same intensity of current flow through its elements.


Where can one purchase CDA appliances from?

Where can kitchen appliances be bought?

You can purchase kitchen appliances at your local Walmart, Target, or Sears. You can also purchase them online through Amazon and have them shipped directly to your house.


Why does the same voltage run through all the branches of a parallel circuit irrelevant of the different resistance appliances on those branches?

The same voltage is present but does not run. It is the current that could be described as "runniing" through the different branches. Just by definition, parallel circuits necessarily have the same voltage. It is architecture of the circuit.
