Explanation: so 9/3=3 current is 3 amperes.
How much current is in a circuit that has a 9 volt battery and a 12 ohm bulb?
=> i = 9/12 = 3/4 ampere currentanswer.
When battery of 9 V is connected across a conductor and the current flows is 1 A the resistance is?
Hence, the resistance offered by the conductor is 90 ohm.
What is the current of the circuit above if you used a 9 volt battery?
In the circuit shown above, the current delivered by the 9-volt battery of internal resistance 1 ohm is 3 amperes.
What is the current when a 9 V battery is attached to a 10 ohm resistor?
If you work this out, the current is 9V/(11.5 ohms) = 0.783A, so the voltage across the 10 ohm resistor must be 7.83V.
When a battery of 9v is connected in series?
Answer Submitted
Equivalent resistance in series = 0.2 + 0.3 + 0.4 +0.5 + 12 =13.4 ohms. Since current through each resistance is same in series combination, so, current in 12 ohm resistance in 9/13.4 amperes.
What is the current in a 10v circuit?
1/R = 1/20 + 1/10 +1/20 = 4/20 = 1/5 ==> R = 5 Ohm. The current through the circuit = 10 volt/5 Ohm= 2 ampere.
How much current flows through a 12 ohm resistor?
hence, 1.5 ampere current will flow through a resistor of resistance 12 ohm, if a battery of 18 V is connected across it.
How does it flow in an electric circuit class 10?
By convention, electric current flows in opposite direction to the movement of electrons. As shown in this figure, electron flows from negative terminal to positive terminal. As a result, electric current flows from positive terminal to negative terminal.
What is the relationship between resistance and current?
The current in a circuit is directly proportional to the electric potential difference impressed across the circuit and inversely proportional to the resistance of the circuit.
How many amps are in 9 volts?
9V batteries have 0.4 to 1.2 Amps. 9V batteries provide 500 milliamps for an hour. A ‘milliampere-hour’ rating shows you the volume of electricity the battery will generate in an hour before it dies.
How many amp does a 9-volt battery have?
A fresh 9-volt battery can put out around 2 amps for a short period of time.
How much current can a 9V battery supply?
A standard 9V battery has about 400-600 mAh capacity. In the most basic terms, these batteries can supply about 500 milliamps for one hour before being “dead”.
When a 9 V battery is connected to a 3 resistor how much current will flow?
3 amperes
Explanation: so 9/3=3 current is 3 amperes.
How many 9 V batteries would it take to give a circuit with a 2 ohm resistor a current of 18 a?
Adding two 9 volt batteries in series will give you 18 volts. Putting a 18 ohms resistor across the two batteries will draw 1 ampere current through the resistor which will dissipate 18 watts of heat. Adding voltages does not give watts.
What equation would you use for current?
Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.
When a 24 V battery is connected to a resistor the current in it is 0.4 a what will be the current through it when it is connected to a battery of 6 V?
Current,I = ? I = 0.1 A .
What is battery Wikipedia?
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode.
What is the current in a 10v circuit if the resistance is 5ω?
Explanation: 10/5= 2 Current =2 amperes.
What happens to the current in a circuit if a 10 ohm resistor is removed and replaced by a 20 ohm resistor?
12. What happens to the current in a circuit if a 10Ω resistor is removed and replaced by a 20Ω resistor? I = 10Ω → 20Ω For the same voltage, current decreases.
What is the current in a 120v circuit if the resistance is 15ω?
8 amperes
So 120/15= 8 amperes.
