Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
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.
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.
If the two 5 ohm resistors were in series, then the current would be 1.2 amperes. If they were in parallel, then the current would be 4.8 amperes. Ohm's Law: Current = Voltage divided by Resistance RSeries = Summation1toN RN RPARALLEL = 1 / Summation1toN (1 / RN)
2 amperes (current = voltage/resistance)
A resistance of 3 ohms connected between the terminals of a 9-volt battery will result in a current of 3 Amperes. If the battery is one of those little ones with snaps on top, it may be able to produce 3 amperes of current for about 3 seconds before it rolls over and totally dies.
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.

The current depends on the total effecvtive resistance of everything connectedacross the battery.If the bulb is the only component there, then the current is E/R = 9/12 = 0.75 amperes.
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
Current = voltage/resistance If those are the only components in the circuit, then Current = 9/12 = 0.75 Ampere = 750 mA

Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
To calculate amperes, you can use Ohm's Law: amperes = voltage ÷ resistance. Current is the flow of electric charge, measured in amperes, that passes through a conductor in a unit of time. You can measure current using an ammeter in a 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.
