The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).

A 9v battery is in a series with a 100 resistor and there is a current of 0.09 a flowing through the circuit what is used by the circuit?
0.81 APEX
What is the current in a circuit consisting of a 1000 ohm resistor with a voltage of 50 volts DC?
Current (I) = Voltage (V) / Resistance (Ohms) I = V/R = 50/1000 = 50 milliamperes or 50 mA
What are the parts of parallel circuit?
Simple parts of a circuit are switches, light bulb, battery and connecting wires.
What is complete circuit?
A complete circuit is where a current can flow without any leaks.
How current electricity moves in a circuit?
You need a source of electrical potential difference, also known as voltage (which is the technical term for what for you call "electric pressure"). The easiest and most common voltage source is a household battery. Hook up the positive electrode of the battery using a conductor (eg. a copper wire) to one end of your circuit and the negative electrode to the other end, and voila, you'll have electric current flowing through your circuit.
Why does a circuit stop working when you remove the battery?
The battery is the power source of the circuit. It supplies current to the circuit and the circuit is simply a path for the current to follow. When you remove the current (battery), the path still exists but there is no current going through it.
Is a car battery a circuit?
Hi, there. A battery is a power supply, a source of potential difference which drives current. In itself, a battery is not a circuit, but if you attach it to a load (a resistance), then a current will form and a circuit is made!
A resistor is required to limit the current taken by a battery when being charged from a 25V dc source. Continued......?
QUESTION (continued from above) ....The battery has negligible resistance and its open-circuit voltage is 20V. Determine the resistance, if the current to the battery is to be limited to 25A.
What is current in the battery called?
A battery contains a charge of electrons. When these electrons leave the battery and travel through a circuit that is described as current.
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
How would the circuit inside a flashlight work?
Flashlight by light, battery, circuit, a hood and a reflective cup, circuit storehouse, switch, etc, the basic principle is the current from the battery, and then to the circuit, after adjusting circuit voltage and current, and then output to the light source for lighting.
Should you connect both ends of a battery in a circuit?
it is necessary to connect both the terminals of a battery to a circuit for current to flow through it..!!
What is an complete circuit?
A circuit is complete whenever current can flow from the battery (or what is producing current), through the circuit, and back to the battery. A complete circuit could contain just a battery and one wire. An incomplete circuit could be a battery with a wire attached to just one terminal, because current cannot flow all the way through the circuit in this case (i.e. cannot flow through the battery). note: not all elements in a circuit may have current flow in a complete circuit. For instance, a light bulb may be shorted but you still have a complete circuit.
What does the electric battery do?
If there is a full circuit, it will send current around it.
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
When the wires are connected to the terminals of the battery what causes electric current in a circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
In an electric current electricity flow how?
Electricity can flow in an electric circuit by a battery. The battery creates electrons, which flow through the wire, and then go into a light bulb. (That is how a light bulb in a circuit lights up.) A series circuit is a circuit with one wire that electrons can flow through. Also, there can be more than one light bulb connecting to the same wire. A parallel circuit is a circuit with light bulbs that have their own wire.ClarificationThe above answer, unfortunately, perpetuates the myth that current leaves a battery, and finds its way around a circuit. This is not the case at all. It is the load that 'draws' the current from the battery and it is the load that determines the size of that current.
