If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes.
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.

Does a resistor only decrease current in a circuit?
A resistor does not only decrease current in a circuit it can also reduce tension(voltage) if connected in series.
When a 12 volt battery is connected across an unkown resistance there is a current of 2.5m amphere in the circuit find the value of resistance of the resistor?
4.8 ohms
What is the current in circuit with 6 v battery and 2 resistor?
3 ampere
How do you install a resistor in an DC circuit?
It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load. To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow. To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True

When electric circuit is closed no current flow through it IS the statement is correct?
yes... this is possible if a diode i connected in reverse bias with a battery and a resistor for example. A diode in reverse bias means its anode will be connected to positive terminal of the battery and its cathode to the negative terminal of the battery. In such a case, minimal current flows through the circuit which can be neglected.
Where do you use the current limiting resistor?
in a flashing led circuit connected in series
If a 1.5 V battery is connected to a 330 Ohms resistor Calculate the current in the circuit?
Ohm's laws says it will be 1.5 vdc divided by 330 ohms.
What is the current in circuit with 6 v battery and 2 resistor?
3 ampere
If two bulbs in a series are connect to a battery and the current in the first bulb is found to be 1 ampere then what is the current through the battery?
A circuit with a 2 ohm resistor and a 4 ohm resistor in series with a 12 volt battery will have 2 amps flowing through each resistor. The current is the same in each resistor because they are in series, and a series circuit has constant current throughout.
What happens when more than one resistor is connected to a circuit?
the current flowing in will be low
What is the relationship between resistance and current in a resistive circuit?
:) It's connected together
When a resistor is connected in parallel what happens to the size of current form the battery?
When a resistor is added the current goes down, that is expressed in the equation current= voltage/ resistance
A 6 volt battery is connected across a 10 ohm resistor what is the current flowing in the circuit?
V = 6 V R = 10 Ohm I = V/R = 0.6 A
What is the current in a 12-volt circuit with a 6-ohm resistor connected series?
2 A (amperes)
