How much current at 240 volts passes through a wire with a resistance of 100 ohms?

current = voltage/resistance
Assuming the 240 volts is across the 100 ohm wire, 2.4 amperes
power = current * voltage
Resulting in the wire dissipating 576 watts... One hot wire!

What is the amperage in an electric circuit when the voltage 120 volts and the resistance is 40 ohms?
Ohm's Law states Voltage = Current x Resistance. You rewrite the equation as Current = Volts / Resistance to solve for current.
What effect are there when resistance is increased in the size of the current?
Current is inversely proportional to resistance. If you double the resistance, you halve the current. Ohm's Law: Volts = Amps * Ohms Solve for Amps: Amps = Volts / Ohms
What voltage is required to sustain a current of 0.50 through a light bulb resistance of 190?
The voltage of a circuit with a resistance of 250 ohms and a current of 0.95 amps is 237.5 volts. Ohms's law: Voltage = Current times Resistance
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 is the value of amperes for 100 volts at constant resistance?
V = I*R, so take 100 volts and divide it by the value of the resistance to get the current. Current is measured in amperes.
How current passes through resistor.?
What is the current running through resistor four?1 amps..!What is the current running through resistor one? 3 amps...!What is the current running through resistor three? 2amps..!What is the current running through resistor five? 3 amps..!What is the voltage drop running through resistor five? 45 volts...!What is the equivalent resistance through the parallel portion of the circuit? 6 ohmsAnswerA resistor is a conductor, albeit one with a higher resistance than a length of wire, so current passes through it without any problem. The magnitude of the current will, of course, be somewhat lower because of the additional resistance.
What voltage required to send a current of 4 amps through a resistance of 60ohm?
16 volts
If the current through a heater coil is 5 amp and the supply voltage is 120 volts the coil resistance is?
The formula you are looking for is R = E/I. Resistance = Volts/Amps.
How much current would an applied voltage of 10 volts cause through a resistance of 5 ohms?
10 volts applied to 5 ohms would cause a current flow of 2 amperes. Current = voltage divided by resistance.
How any volts are produced in a circuit with 40 amp's of current flowing through a wire with 5 ohms of resistance?
It is a voltage (potential) applied to a load that causes a current to flow through the load. Ohm's Law encapsulates this principal and states Volts = Current x Resistance. In your example, the applied voltage would be 200 volts.
What are the three electrical guantities?
The three electrical quantities are current voltage and resistance. Current is measured in amperes (A) and is the rate at which electricity flows through a conductor. Voltage is measured in volts (V) and is the electrical force pushing the current through the conductor. Resistance is measured in ohms () and is the opposition to the flow of current. Current - measured in amperes (A) Voltage - measured in volts (V) Resistance - measured in ohms ()
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
Calculate the voltage of required to push eleven amperes through a 20-ohm resistance?
U = RxI so 11x20=220 volts
What is the current through a wire that has a resistance of 30 ohms if the voltage is 45 volts?
If the resistance of the wire is 30 ohms and the voltage between the two ends of the wire is 45 volts,then the current through the wire isI = E/R = (45/30) = 1.5 amperes.
In an electric circuit resistance is?
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
How much current will flow through a 12 ohm resistor if 6 volts are applied across it?
Voltage / Resistance = Current, you do the math
Would it be true to say that current causes voltage?
Volts = Current x Resistance. The voltage is where the potential resides for the amount of current flowing through a resistance. Think about the voltage as a potential source of electrons that then flow through a circuit depending on the Load, or resistance in this example.
