3 ohms. 9 volts across a 3 ohm resistor becomes 9/3 or 3 amps.

If a toy car with a resistance of 2 ohms is connected to a 3v battery how much current flows through the car?
Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).
How will you describe the graph of resistance against current?
If resistance is high that time the current flow is low. Bcoz current always flow through the low resistance path.
What is the meaning of IR of voltage?
In Ohm's Law, E stands for voltage, I stands for current (amps), and R stands for resistance. Ohm's Law states: E = IR or voltage equals current times resistance. This means that current flowing through a wire (that has resistance) produces a voltage drop in the wire. Since the voltage drop is the result of current flowing through a resistance, old-school engineers will sometimes refer to it as "IR drop". So, since E = IR, saying "IR" is the same as saying "voltage".
A 3 Volt battery sends a current of 0.10 A through a light bulb what is the resistance of the filament of the bulb?
Volt (V) = Resistance (R) times Current (I) therefor R = V / I 30 Ω = 3V / 0.1A
What is electronic resister?
Electronics resistor are a basic passive element it oppose the flow of current . the opposition depend upon the value of that resistance high value resistance will only able to flow some few amount of current through them. but low value of resistance allow to flow large current through them.
A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
A wire with resistance R is connected to the terminals of a 30 V battery. What is the current through the wire if the wire has the resistance?
Your current will be 30/R Amps. Where R is the resistance in Ohms.
Why do batteries get warm?
Because they have internal resistance. Current flow through this internal resistance produces heat, just like current flow through ordinary resistors does. The current can be from use of the battery or charging the battery (if it is rechargeable). Usually the internal resistance of a battery increases with age, meaning older batteries tend to run hotter than fresh ones.
What is lost volts?
A battery is rated to supply a certain number of volts. However, it actually supplies less, because they are "lost" as the current has to get out of the battery in the first place.(The battery has internal resistance)The amount of lost volts depends on the current being drawn:The less resistance a circuit has, the more current is drawn, because it's easier to flow.Example:If the circuit has little resistance, it draws a large current and the battery's internal resistance causes more lost volts.If the circuit has high resistance, it draws a small current and there are fewer lost volts.This is why when you short-circuit a battery (give it hardly any resistance to go through) it heats up and may explode. A large current is drawn and all the volts are used by the battery's internal resistance.
What is the electrical resistance offered by a current-carrying element that produces a drop of one volt when a current of one ampere is flowing through it?
One ohm.
How do you convert galvanometer to ohmmeter?
Ohms are the unit of measurement for resistance, so an ohmmeter is a device that measures electrical resistance. A galvanometer measures the current flowing through the resistance, so the two are related. To convert a galvanometer into an ohmmeter, one needs an external battery.
Unit of electric resistance?
The unit of resistance is the 'Ohm'. A conductor through which a current of 1 ampere produces a voltage drop of 1 volt has a resistance of 1 ohm.
1 A current of 0.88 A flows through a lamp when it is connected in series with a 6 V battery What is the resistance of the lamp?
The formula you are looking for is R = E/I. Resistance is stated in ohms.
When a multimeter is set to measure resistance?
it determines how well the current flows through the wires. ANSWER: When there is no outside power connected to it. But some power is necessary to read the resistance so the meter battery will supply the current necessary to measure the IR drop and translate that to resistance
What is the current produced with a 9-volt battery through a resistance of 100 ohms?
Current I = V/R V = 9V R = 100ohm I = 9V/100ohm = 90mA
What is meant by resistance of a current?
The resistance of a current is a measure of how difficult it is to push the electrons along.AnswerThere is no such thing as the 'resistance of a current'. Resistance is a characteristic of the material through which a current flows, not of the current itself.
What do you mean by heating effect of current?
The heating effect of current refers to the phenomenon where the flow of electric current through a conductor leads to the production of heat. This occurs due to the resistance offered by the conductor to the flow of electrons. The amount of heat produced is directly proportional to the square of the current and the resistance of the conductor.
