What is the effect of varying resitance in parallel affect current?

Varying the resistance of one branch of a parallel circuit will vary the current through that branch without affecting the currents in any of the other branches. As the supply current is the sum of the branch currents it, too, will vary.

And also the voltage across the elements which are connected parallel are same and current through every branch varies and it should obey the kirchhoff's law. Having said that it will definitely affect the voltage and current distribution.

How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
How does adding devices in parallel affect the current flowing in the circuit?
It divides the current according to the resistances ( inversely proportional) of the devices but the potential difference across each remains the same.AnswerEach branch draws its own current. The sum of the branch currents will equal the supply current. Adding another branch will act to increase the supply current by the amount of current drawn by the new branch.It's a mistake to say that the branches 'divide the current', which suggests that the supply current is constant and is then distributed between the branches.
How does increasing the resistance affect the current?
Increasing resistance decreases current.
How can a broken wire affect a series circuit differently than a parallel circuit?
In a series circuit, all the current passes through the one circuit. Any break will totally remove power from all of the circuit.Parallel circuits have more than one branch where the current can flow. A broken wire will only affect one part, the rest of the circuit will still pass current.In a series circuit, all the current passes through the one circuit.

How does the number of bulbs affect the amount of electrisaty in a circuit?
Adding additional lamps has no effect on the supply voltage supplied to you home. If the lamps are connected in series, then the sum of voltage-drops appearing across each lamp will equal the supply voltage. If the lamps are connected in parallel, then the voltage across each lamp will equal the supply voltage.

How does connecting devices in parallel affect the electric current in a circuit?
it doesn't, the one with the highest resistance does
Does an electric current affect weight?
No, an electric current does not affect weight.
Does varying the either the wavelength or frequency affect the speed of the wave in that medium?
No.

Should an ammeter always be connected in parallel with a component?
No, an ammeter should never be placed in parallel with a component - it should always be placed in series, so that the current through the component is measured.If you place an ammeter in parallel with a component, you create a short circuit around the component. Depending on the rest of the circuit, you could damage the circuit, damage the ammeter, create a fire, etc. You certainly will affect the current through the component, and that is not what you want to accomplish.
How does the number of cells affect the current in a circuit?
More cells = more available power. Power = voltage * current. The orientation of the cells determines whether this power is delivered as more voltage, or more current. If the cells are in series, the voltage will increase proportionately and the available current will remain unchanged; if the cells are in parallel, the current will increase proportionately and the voltage will remain unchanged.

Are the lights in your school connected in series current or parallel current?
Overhead lights are typically connected in parallel. If they were connected in series, then, if one light went out, all of the lights would go out. Think of Christmas lights, they are connected in series. When one of the lights burns out, the whole string of lights goes out.

How does gravity affect motions in softball?
well pitching they help! depending on what pitch your throwing! especially a drop ball because gravity wants to pull it down anyway! and the air resitance makes other pitches move!
