The equation, I=V/R (Current = Voltage/Resistance) determines the current, so if you increase both V and R, you will be able to get the same current (with a bit of adjustment to make it exact)

example:

10 Volts & 2 Ohms resistance = 5 Amps Current

20 Volts & 4 Ohms resistance = 5 Amps Current

Explain the rheostat and its advantages in electric circuits?

Advantages in electric circuits : Advantages of using the rheostat in electric circuits is optional as you could just use the dial on the power-supply to vary the voltage (p.d.), and therefore the current. The advantage of using the rheostat is that you can control it to give you nice even numbers for the voltage.


A fuse is a device used to keep electrical circuits from overheating?

A fuse is a device used to keep electrical circuits from overheating is not a true statement. A fuse is used to protect the wire of the circuit from an over current being applied to the circuit. This over current could be caused by a couple of scenarios. Two non insulated conductors touching one another and creating a short circuit. Another cause could be an non insulated conductor touching adjacent grounded equipment. Whatever the cause the fuse will isolate the fault instantaneously.


What happens if wire insulation is weak?

Depending on the voltage potential that the wire is carrying, an insulation breakdown could lead to a short circuit. If this condition occurs then the circuits over current protection should trip the circuit off line.


Is it ok to run three 240 on one 50 amp breaker?

If you are asking, can three separate 240 volt circuits be run off of one 50 amp breaker then the answer is no. Not without knowing what the loading of the three circuits are and whether all three circuits could be on at the same time.


What is AD current loss?

AD current loss could refer to a comic, called Eddy Current. It could also refer to AD loss, memory loss caused by Alzheimer's Disease.

What are some different types of electrical circuits?

Some different types of circuits are:openclosedparallelseriesThere are two types of basic circuits, series and parallel.In series, current stays constant and voltage is divided amongst the resistors.In parallel the voltage stays constant, Every branch of the circuit gets the same voltage from the power supplier, but there is different current in every branch but current doesn't get lost. Current entering a junction(branches) must equal to current out of the junction. Iin =Iout.The third type could be the Series-Parallel Combination, which has some components wired in series and other components in parallel. Solving these circuits requires more complex analysis techniques. See related link.Another AnswerElectrical circuits are generally classified as being: (1) series, (2) parallel, (3) series-parallel, and (4) complex. The term, 'complex' is a category into which any circuit that doesn't fall into the first three categories, is placed.

Effects of connecting poor contact in electrical circuits?

An effect of connecting a poor contact in an electrical circuit could be intermittent current flow.


What do you use fuses in?

Electrical circuits, to limit the maximum current flow. Fuses will "blow", or burn out, and cause an open circuit, to stop the flow of current when it could potentially damage a circuit, system, or device.

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.


Why are fuses and curcuit breakers used in household circuits?

Fuses and circuit breakers are used to protect the wiring and devices from overload and heating caused by short circuits, short circuits that, if unprotected, could cause major damage and/or fire due to excessive current.


Why does your dashboard lights work but not your headlights?

The headlights could have bad bulbs or a bad fuse; the two sets of lights are on different circuits.


What are some parallel circuits practice problems that can help me improve my understanding of electrical circuits?

One practice problem for understanding parallel circuits is to calculate the total resistance in a circuit with multiple parallel branches. Another practice problem could involve determining the current flowing through each branch of a parallel circuit. Additionally, you could try calculating the total power consumed by the components in a parallel circuit. These practice problems can help improve your understanding of electrical circuits.


What statements is not correct about the elements in a circuit?

One incorrect statement about elements in a circuit could be that capacitors always slow down the flow of current. In reality, capacitors can both store and release electrical energy, affecting the current flow in different ways depending on the circuit configuration.


Did one leg of your 1950's 100A main breaker fry because it was overloaded by too many dedicated circuits?

It is possible that one leg of the 100A main breaker may have fried due to being overloaded by too many dedicated circuits in the 1950s setup. If the circuits were drawing more current than the breaker could handle, it could have caused overheating and damage to that leg of the breaker.


Which effect of current does the fuse wire in electric circuits utilize?

The heating effect is used. Normally the current flows through the fuse without undue heating. But if too much current passes through, the fuse will heat and melt, thus stopping the current which could cause a fire if it was not stopped.
