A 14 ohm conductor measures a current of 20 amps what is the voltage?
14 ohm X 20 A = 240 V (V=IR) the answer is 280 14x20 is 280!
8 ohm element that operates a 240 volts the power that's consumed is?
Assuming a pure resistive load Ohm's Law tells us 240 / 8 = Current = 30 Amps. Watts = Volts x Amps so 240 x 30 = 7,200 Watts = 7.2 KW.
How much current at 240 volts passes through a wire with a resistance of 100 ohms?
current = voltage/resistanceAssuming the 240 volts is across the 100 ohm wire, 2.4 amperespower = current * voltageResulting in the wire dissipating 576 watts... One hot wire!
What is the unit and abbreviation of current and resistance?
The unit of Current is Ampere. Abbreviation of Current is 'I' and that of Ampere is 'A'. The unit of Resistance is ohm. Abbreviation of Resistance is 'R' and that of ohm is the symbol of 'omega' or the symbol of 'ohm'.
How much current flows through a 12 ohm flashlight bulb operating at 3.0 volts?
Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.
A hot-water heater has an 8-ohm element that operates at 240 V The power that's consumed by this water heater is?
VOLTS x (VOLTS/OHMS) = WATTS 240 X (240/8) = 7200 Watts = 7.2KWatts
A 75 ohm light and a 150 ohm heater are connected in parallel to a 150 volt power source. What is the current through the 75 ohm lamp?
2 amps
How much current will an electric heater draw from a 110-volt line if the resistance of the heater when hot is 26.7 ohm?
4.12A. V=IR
A 14 ohm conductor measures a current of 20 amps what is the voltage?
14 ohm X 20 A = 240 V (V=IR) the answer is 280 14x20 is 280!
What is the wattage of a 240V 500W heater when derated to 120V?
41.6
8 ohm element that operates a 240 volts the power that's consumed is?

What will happen if an electric water heater which is designed for operation at 240 volts is connected to 120 volts?
240 heater on 120 volts The load is a resistive load and as such it is governed by Ohm's law. Current is directly proportional to the voltage and inversely proportional to the resistance. As the voltage goes down so does the current. For example take a 2200 watt heater at 220 volts = 10 amps. R = E/I = 220/10 = 22 ohms of resistance in the heater. Now take the 2200 watt heater and using the same formula and at 110 volts. I = E/R, Amps = Volts / Resistance. 110/22 = 5 amps. As you can see ohm's law holds true, the current is inversely proportional to the resistance and as the voltage goes down so does the current. To answer the question, yes a 220 volt heater will run on a 110 volt circuit but at 1/4 of the wattage that the heater is rated at. W = A x V = 5 x 110 = 550 watts.
What is the resistance of a lamp operating at 115 volts and using 0.25 amperes of current?
The resistance of a lamp operating at 115 volts and using 0.25 amp of current is 460. The relationship I used is Ohm's law.
How much current at 240 volts passes through a wire with a resistance of 100 ohms?
current = voltage/resistanceAssuming the 240 volts is across the 100 ohm wire, 2.4 amperespower = current * voltageResulting in the wire dissipating 576 watts... One hot wire!
What is AC ohm's low?
ohm's law state that in an electric current it is propotional to current
A ohm light and a 150 ohm heater are connected in parallel to a 150 volt power source. what is the total resistance of the lamp and the heater?
50 ohms...!
Q: A 75 ohm light and a 150 ohm heater are connected in parallel to a 150 volt power source what is the equivalent resistance of the lamp and the heater?
50
