Is An open in the main line of a parallel circuit causes all individual branch currents to be zero?
Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
What will happen if more bulbs are added to a circuit with one cell?
YESAnswerNot necessarily. The current depends on the potential difference and the load resistance. If you connect cells in parallel, you do not effect its voltage or the load, so the current is unaffected (although the battery's current 'capacity' will increase). If you connect the cells in series, then you will increase the voltage and the current will increase.
If voltage changes in a ac circuit what happens to current?
Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.
A complete electric circuit includes a voltage source current wires and something to ground the flow of current?
If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit. Leave any one of these things out and you will not have a complete circuit.
How can the current flowing in a electric circuit be increased?
we have to increase the winidin count of Coils inside the Alternator and also the Carbon mesh brush is to be increased so that the higher electric output will be produced................
How can you make an electric current stronger?
An electric current through a resistive circuit can be increased by decreasing the resistive load or increasing the voltage of the circuit.
How is an ammeter connected in a circuit in order to read the current flowing in the circuit?
In series with the circuit and never in parallel. The reason being that it will cause the circuit total resistance to drop which will make the circuit draw excessive current. That's a short circuit actually.
What function in a circuit for a switch?
A switch is a make - break device. Its function is a circuit is to make and break the current flow of the circuit that it is in. This action then starts and stops the load that is connected in the circuit.
Why does a switch make a light turn on and off?
The purpose of a switch is to stop and start a current flow in a circuit. The stopping of a current flow in a circuit effects the load of the circuit by stopping its action. Resuming the current flow in a circuit also resumes the action of the load.
Is An open in the main line of a parallel circuit causes all individual branch currents to be zero?
Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
How do you build a circuit?
Three main components that are needed to build a circuit will be a power source. This supplies the circuit with a voltage to operate. A load to make the current flow through the circuit, and conductors to join these two devices together to carry the current.

If you connect cells in parallel, you do not effect its voltage or the load, so the current is unaffected (although the battery's current 'capacity' will increase).

What happens to the current in circuit as the resistance increases?
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
How much current is need for 12 VDC to flow through water?
First thing voltage does not flow current does. Voltage is the potential or pressure needed to make the current flow. Current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. To make the current flow you have to adjust the resistance of the circuit and that would be the water in this case. Salt added to water will make the water conductive so the resistance can be adjusted thereby making the current rise or fall depending on the water solution's resistive properties. The equation that you should consider using is Amps = Volts/Resistance.

How can you make a current smaller in a circuit?
Taking some bulbs out of the circuit!! (I think :P) Taking some bulbs out of the circuit!! (I think :P) Use Ohm's law I = E/R. Add some values and check it out. You use the formula V = IR (where V and E are the same thing, voltage. I is the current. R is the resistance). If you add more resistance then your current will be lower. I would suggest looking at parallel and series resistance so that you can understand equivalent resistance.
