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.

What is added to a circuit to make the current smaller?

The reduction of voltage or the increase of resistance will reduce the current in a circuit.


What effect would thinner wire have in a circuit?

The smaller the wire size used in a circuit limits the amount of current that is allow to be flow through that circuit.


How current transformer measure current?

A current transformer doesn't 'measure current'. It merely reduces a large current flowing through its primary to a smaller current which can be read by an ammeter connected to its secondary. At the same time, it electrically isolates the secondary circuit from the primary circuit, which is essential if the primary circuit is part of a high-voltage system.


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


The differences between a series circuit and a parallel circuit?

In a series circuit, electrons flow through all the components one after another. If one fails (break), the whole circuit is no longer live. All the resistances are also added up in a series circuit. The current (measured in amps) is the same throughout the whole circuit. In a parallel circuit, electrons flow through smaller circuits all coming from the same source. The amperage is different in each circuit based on the resistance offered. The one wire running to all the smaller circuits has higher current than any of the small offset circuits. Removing one thing will not affect the other smaller circuits as electrons can still flow. Current will be affected, of course.


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.


Why reducing current in circuit?

The current in a circuit is reduced to prevent the circuit from over load.


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.
