How many volts are required to push 3 amps through a resistance of 4 ohms?
Just use Ohm's Law: V=IR (voltage = current x resistance; using units: volts = amperes x ohms).
If you multiply electric current times resistance what will it be in units?
That depends on what units you use as input. If you put in current in Amps and Resistance in Ohms you will get voltage in Volts.AnswerCurrent is measured in amperes. Resistance is measured in ohms, which is a special name given to a volt per ampere. Multiply amperes by (volts per ohm), and you are left with volts.
If a current of 2 amps flows through a 12 ohm resistor what is the voltage across the resistor?
V = (I) x (R) = 2 x 12 = 24 volts
What is the current when a 12 volt battery is connected through a resistance of 25 ohms?
The current flowing through the circuit can be calculated using Ohm's Law: I = V/R, where I is the current, V is the voltage (12 volts), and R is the resistance (25 ohms). Plugging in the values, the current would be 0.48 amperes.
What is the resistance when a bulb has a current of 5 amps and a voltage of 12 volts?
The resistance can be calculated using Ohm's Law, which states that resistance (R) equals voltage (V) divided by current (I). In this case, R = 12V / 5A = 2.4 ohms.
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.
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.
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
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 ()
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.
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 formula for electrical resistance?
Resistance(Ohms)= Voltage(volts)/Current (Ampheres) -X
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.
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.
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.
What is the voltage if the current is 0.4 A and the resistance is 3?
To find the voltage, you can use Ohm's Law, which states that Voltage (V) = Current (I) × Resistance (R). Given a current of 0.4 A and a resistance of 3 ohms, the voltage would be V = 0.4 A × 3 Ω = 1.2 volts. Therefore, the voltage is 1.2 volts.
If the voltage is 5 volts and resistance is 25 ohms what is the current flow?
0.2 volts
