When Resister is 120 volts and the current through the resister is 0.5 Amps determine the value of the resistor in ohms?
Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
What will be the voltage drop across each what resistors A 160 Ohms B 100 Ohms C 82 Ohms D 120 Ohms.?
Ohm's Law requires you know two of three parameters to calculate the third. Volts = Amps x Ohms You need to know current flowing through resistance to calculate voltage drop.
What ohm value or what combenation of resistors are needed to draw 20amps at 120v?
ohms = volts/amperes 6 ohms = 120 volts / 20 amperes
Led circuit for 120 volts?
There can be no answer for this without knowing how strong a resistor is involved. (Ohms)
If the potential difference across a load is 60 volts and the resistance of the load is 10 ohms the current is amperes.?
It's not that simple. The basic formula is Volts / Ohms = Amps. For 30 Volts you'd get 0.5 Amps, for 60 Volts you'd get 1 Amp, for 120 Volts you'd get 2 Amps.

Calculate the resistance of a bulb that draws 0.6 A of current with a potential difference of 3 V?
V = I.R R = V/I R = 110/0.5 R = 220 Ohms
What is the resistance of metal conductor with a current of 2a and connected to a source providing potential difference of 120v?
R = E / I = 120/2 = 60 ohms.
What is the resistance of a 120-W incandescent lamp connected to a 120-V power supply?
The resistance of the lamp can be calculated using the formula: Resistance = (Voltage)^2 / Power. Plugging in the values gives: Resistance = (120 V)^2 / 120 W = 120 ohms. So, the resistance of the 120-W incandescent lamp connected to a 120-V power supply is 120 ohms.
How is the rating of a light bulb determined for instance 100W 60W is that how many watts an hour to run it?
No, the wattage is determined by the resistance of the filament in the light bulb. The formula to determine the wattage is Watts = Voltage (squared)/Resistance in Ohms. To find the resistance of a 120 volt light bulb use the formula, Resistance in Ohms = Voltage (squared)/Watts. So for a 100 watt bulb at 120 volts the resistance is 120 volts x 120 volts = 14400/100 = 144 ohms. For a 60 watt bulb at 120 volts the resistance is 120 volts x 120 volts = 14400/60 = 240 ohms. As you can see this holds true to Ohm's law, current is inversely proportional to the resistance of the circuit. The higher the resistance of a load, the harder it is for the current to flow. In this case less current results in less light being emitted from the filament in the light bulb.
What is the resistance of a conductor that carries a current of 120 amperes when the potential difference between its ends is 240 volts?
The resistance of the conductor can be calculated using Ohm's Law: resistance (R) = voltage (V) / current (I). Plugging in the values gives: R = 240 V / 120 A = 2 ohms.
What is 120 as a percent of 100?
120 is 120% of 100.
Voltage drop - explanation in terms of electrons?
Voltage drop is the decrease in electrical potential energy of electrons as they move through a circuit due to resistance. When electrons encounter resistance, they transfer some of their energy to overcome it, resulting in a decrease in voltage along the circuit. This drop in voltage is proportional to the resistance in the circuit and can affect the performance of electrical components.
Definition for tolerance value of a resistor?
An allowable amount of variation on either side of specified measure. If a resistor is labelled as 100 ohms, with 20% tolerance, it might be anywhere from 80 to 120 ohms. If a resistor is labelled as 100 ohms with 10% tolerance, it should range between 90 and 110 ohms. If a resistor is labelled 100 ohm with 5% tolerance, it could vary between 95 and 105 ohms. A tolerance is both ways, if a measure has 10% tolerance, then the total variation is 20%, plus 10 added to minus 10. If you are talking about variation to one side alone, the term is "deviation". If a resistor is supposed to be 100 ohms and actually tests at 105 ohms, it deviates by 5%, but is within allowable variation if it is specified to be within 5% tolerance.
