In the U.S. 120 volts.
<<>>
Using the equation E = I x R, Volts = Amps x Resistance = 110 volts.

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 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 is the current in the overall circuit?
volts/resistance=current. Ohm's law
What is the resistance of a 120-W incandescent lamp connected to a 120-V power supply?
Power (watts) = current (amperes) * voltage (volts) Current (amperes) = voltage (volts)/resistance (ohms) 120 watts = current * 120 volts current = 1 ampere 1 ampere = 120 volts/resistance resistance = 120 ohms
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.
If the voltage is 5 volts and resistance is 25 ohms what is the current flow?
0.2 volts
110v and the current is 10 a what is the resistance?
Resistance is Volts over Current 11 Ohm = 110Volt / 10 Amp
If a 325 watt heater has a current of 6.0A what is the resistance?
Watts = Current x Volts with your resistive heat application. To figure out resistance you need to know voltage and current. Since you are drawing 6 amps then Volts = 325/6. This means that there is about 54 volts supplying the heater which seems like a very strange supply voltage. Since Volts = Current x Resistance the resistance = 325/36.
What is the formula for electrical resistance?
Resistance(Ohms)= Voltage(volts)/Current (Ampheres) -X
In a circuit is current proportional to resistance?
Ohms law is: I = V / R (current = voltage / resistance)... where if the voltage or resistance changes then the current will change. ... the current and resistance is a inversely proportional linearly relationship ...this means that if the resistance doubles then the current halfs, if the resistance halfs then the current doubles, etc...hope this helps
What muct be known to calculate current using Ohm's law?
I(current) = V(voltage)/R(resistence) Example : 220 V / 5000 Ohm = 0.044 A (Ampère) = 44mA
What is the equation of resistance?
Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.
