What else can I help you with?
If a circuit has a resistance of 4 ohm's how much voltage is needed to produce a 1.4 current in the circuit?
Voltage across a resistance = (resistance) x (current through the resistance) =4 x 1.4 = 5.6If the ' 1.4 ' is Amperes of current, then the required voltage is 5.6 volts.
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
What word describes how difficult it is for electricity to flow through a circuit?
The word that describes how difficult it is for electricity to flow through a circuit is "resistance." Resistance is measured in ohms and determines how much current will flow for a given voltage. Higher resistance means less current flows, while lower resistance allows more current to pass through.
How much resistance is in the circuit if it uses a current of 0.01 A?
There is insufficient information in the question to properly answer it. You need to specify, also, the voltage, in order to determine resistance from current. Please restate the question. Ohm's Law: Resistance = voltage divided by current.
Does increasing the resistance increase the electric current?
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
How much power is dissipated by a circuit with 15000 ohms of resistance and 10mA of current?
15 KOhms times 10 mA = 150 volts. 150 volts times 10 mA = 1.5 watts.
How much resistance does a light bulb create if it has a current of 25 mA around it in a 9 V circuit?
how much resistance does a light bulb creat if iyt has a current of 25 mA around it in a 9 V circuit?
The number of ohms in a circuit is a measure of the?
resistance to the flow of electrical current in the circuit. It is a measure of how much opposition the circuit presents to the flow of electricity. The higher the number of ohms, the greater the resistance in the circuit.
If a circuit has a resistance of 4 ohm's how much voltage is needed to produce a 1.4 current in the circuit?
Voltage across a resistance = (resistance) x (current through the resistance) =4 x 1.4 = 5.6If the ' 1.4 ' is Amperes of current, then the required voltage is 5.6 volts.
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.
How do you figure out how much current is in an electrical wire?
If you know the voltage and resistance, then current = voltage divided by resistance. Otherwise, you can attach an ammeter into the circuit (in series).
Can inserting a resistor in a circuit have an effect similar to an open circuit?
If the resistance is large enough, then there might not be enough voltage difference to allow much current. Since, Voltage = Current * Resistance, if resistance goes really large, and your voltage doesn't change, your current must decrease. An open circuit is where you do not have any current flowing, so whether no current verses very little current is the same is up to you.
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
How much available current in a 9 volt battery?
It depends on the resistance of the circuit, as V=IR, so I=V/R (V=Voltage, I=Current, R=Resistance)
What is resistance and how is it defined in electrical terms?
Resistance is the measure of how much a material or component opposes the flow of electric current. In electrical terms, resistance is defined as the ratio of voltage to current in a circuit, measured in ohms.
What word describes how difficult it is for electricity to flow through a circuit?
The word that describes how difficult it is for electricity to flow through a circuit is "resistance." Resistance is measured in ohms and determines how much current will flow for a given voltage. Higher resistance means less current flows, while lower resistance allows more current to pass through.
How much current is in a circuit that includes a 9-volt battery and a bulb with a resistance of 12 ohms?
Current = voltage/resistance If those are the only components in the circuit, then Current = 9/12 = 0.75 Ampere = 750 mA
