An electric DC circuit is attached to a 12 volt battery and has a 3 ohm resistor in it find the current flowing through the circuit?

If the 3-ohm resistor is the ONLY thing in the circuit, then the current flowing through it is (12 volts)/(3 ohms) = 4 amperes. If there are other things in the circuit besides the resistor, then the current depends on all of them.


An electric dc circuit is attached to a 12 volt battery and has a 3ohm resistor in it What is the current flowing through the circuit?

The current depends on the total effecvtive resistance of everything connectedacross the battery.If the resistor is the only component there, then the current is E/R = 12/3 = 4 amperes.


A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?

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.


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.


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


A can be used to reduce the current in a circuit?

A resistor.


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.


What do a resistor do in a circuit?

A resistor is a device that impedes or limits the flow of electrical current in a circuit. It converts the current's electrical energy into heat (thermal) energy. A resistor reduces the amount of energy in a circuit and pumps it out as a heat.

What is a function of a resistor in a fire alarm circuit?

A resistor in a sensor circuit is used as a simple way to monitor the function of the circuit. The resistor has a calibrated and known voltage drop and current while the circuit is "normal". If there is a short-circuit, or an open-circuit, the voltage and current will change and trigger the trouble alarm.
