Typically in the US, voltage is +/- 110-120 volts AC RMS (so you can get 240 total), and a typical service will be 100 Amps (I believe, but I could be wrong on "typical" here). This doesn't mean the home uses 100Amps, it means this is the peak amount the home is allowed to draw.

What is Magnitude of the voltage or current?
"Magnitude" means how strong it is - how much voltage (how many volts), or how much current (how many amperes).
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).
An electric heating element has a resistance of 16ohm and is connected to a voltage of 120v How much current will flow in the circuit?
Ohms law states that E=I * R, or voltage equals current times resistance. Therefore current equals voltage divided by resistance. 120v divided by 16 ohms equals 7.5 amps.
How much current flows through a resistance of 300 ohms if the power source is 15 volts?
Ohm's Law Voltage = Current x Resistance Answer is 15/300
What is the importance of determining of resistor values?
it is used to check or verify how much current pass through the circuit using voltage source.
How much current does a 23 watt bulb consume?
To answer this question a voltage must be given.
What is the meaning of 'voltage drives current'?
Think of Voltage as the pressure and Amperage (current) as flow. If you think of it as pipes with water then the pressure would be voltage, and current would be how much water flows past a certain point in the pipe in a given time.
Is a property that determines how much current will flow for a given source voltage whereas a is a device that controls the current in a circuit.?
Resistance is the property that determines how much current will flow for a given source voltage, measured in ohms. A resistor is a passive electronic component that is used to control the current in a circuit by offering a specific amount of resistance to the flow of electricity.
What is Magnitude of the voltage or current?
"Magnitude" means how strong it is - how much voltage (how many volts), or how much current (how many amperes).
Given a circuit has voltage supply of 12Volts and load resistance of 20ohms how much current is expected?
v=ir 12=i20 i = 0.6 Amp
Why does the voltage need to be so high in a power station?
In long range,electric current can flow only when the wires are given high voltage.The voltage is about 20-30kV.eg.lightning. ---------------------------------------- Current of any voltage can flow in a wire. However, the larger the current is, the larger the resistance to flow and the greater the loss of energy during transmission. Therefore, to transfer the same amount of energy per second (power) without as much loss of energy due to resistance, current needs to be lowered by increasing the voltage since Power = Current * Voltage.
How much current flow in 1 watt bulb?
Everything Depends on the voltage supply ...... Current flow (Amp) = Watt / Voltage the Current flow will be 1 amp if voltage is 1 V the Current flow will be 0.5 amp if voltage is 2 V the Current flow will be 0.25 amp if voltage is 4 V and so on.......
How much current was in the circuit?
I'm sure I can answer this if given more details, what circuit? current is determined by voltage and impedence(resistance) in a purely resistive circuit it is pretty basic, in alternating voltage circuits the impedence is dependent on the frequency of the voltage/current. inductors and capacitors are designed into a/c circuits to force the load to behave like a resistive circuit which boils down to how much voltage divided by how much resistance you have, 120 volts divided by 10 ohms equals 12 amps. in a parallel circuit it works pretty much the same way voltage placed on the resistor divided by its resistance equals the current flowing through that leg. more details please.
How much transient current for 930 kw motor?
The current depends on the supply voltage.
What is Difference Between Current Source and Voltage Source?
A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
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).
Why must an LED always have a resistor connected in series with it?
An LED usually has a resistor connected in series with it because an LED (light emitting diode) is not linear in current to voltage (like a resistor) and has to be operated within specified current and voltage conditions. In most circuits the supply voltage is higher than the forward voltage of the LED so the LED would burn up from too much current without a current limiting resistor in series. The resistor sets the voltage and current to a good operating point (voltage and current) for the LED by dropping some voltage across it. The operating point varies depending on the size, type and manufacturer of an LED so the LED's data is used to select the right resistor size for a given voltage source.
