An electric heating element has a resistance of 16ohm and is connected to a voltage of 120v How much current will flow in the circuit?
Ohms law states that E=I * R, or voltage equals current times resistance. Therefore current equals voltage divided by resistance. 120v divided by 16 ohms equals 7.5 amps.
what is the resistance of circuit with 120v and 10A?
12
Example of electric potential?
120v
What is the resistance of a 1100 W 120V hair dryer?
Resistance=Voltage2/Power =1202/1100 =13.1 (3sf)
What is the wattage of 3A 120v Electric Fan?
360 watts
A microwave oven uses 1000 W of power The voltage source is 120V What is the current flowing through the microwave?
I = P/V = 1,000/120 = 81/3 Amp.
You are building a new house and trying to decide between 120v and 240v which is better More practical?
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
Where can you find a 120V electric power cable?
One can find a 120V electric power cable in stores such as Lowe's or Home Depot. It can also be purchased online through the store websites or through sites like rakuten for a cheaper price.
What is the resistance of a circuit with 120V and 1A?
You are mad idiots fools
Why would a high watt lamp draw more current than a low watt lamp?
Power is measured in Watts, power (Watts) = E (volts) x I (current - amps) current is determined by the internal resistance (R) of the lightbulb, the lower the resistance the more current will flow. 120v x 0.5a = 60W 120V x 0.83a = 100W the 100W lightbulb will draw more current We also have Ohm's law: E(volts) = I (amps) x R (ohms) Household voltage stays the same at 120v we have for a 100w lamp: 120v = I x R R = 120v/0.83 amps R = 144.6 ohms for a 60w lamp: 120v = I x R R = 120v/0.5 amps R = 240 ohms The higher watt lamp has lower resistance.
What is the resistance of a clothes iron that draws a current of 12A at 120V?
By Ohm's Law Voltage = Current x Resistance R = V / I = 120 / 12 = 10 Ohms
What are the power requirements, and how do they rank with other similar electric drills?
Electric drills typically require 60-120V DC grounded power cables.
