To find the current in a circuit, you can use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). In this case, with a voltage of 120 volts and a resistance of 20 ohms, the current would be calculated as follows: I = V / R = 120V / 20Ω = 6 amps. Therefore, the current in the circuit is 6 amps.

How much current can be drawn from a 120 volt wall power outlet?
The amount of current that can be drawn from a 120-volt wall outlet typically depends on the circuit's amperage rating, which is usually 15 or 20 amps for standard residential circuits. For a 15-amp circuit, the maximum current is 15 amps, while for a 20-amp circuit, it is 20 amps. This means that the maximum power available from a 15-amp outlet is about 1,800 watts (120V x 15A) and 2,400 watts from a 20-amp outlet (120V x 20A). However, it’s important to avoid overloading the circuit to prevent tripping breakers or creating fire hazards.
What size breaker to use for a hand dryer its 120v 20amps?
For a 120V hand dryer with a rating of 20 amps, use a 20 amp breaker to match the device's ampacity and prevent potential overloading or overheating issues.
Can you convert a 30 amp 120V RV receptacle into a normal 120V outlet?
You can, but your circuit will be "protected" by a 30 amp breaker. So you'll have to consider the safety issues of having wiring and appliances that can draw up to 30 amps before tripping the breaker. Will the wiring and circuity support that much current without damage? If not, then switch to a 15 or 20 amp breaker.
Could 12 gauge wire is used on a 20 amp circuit at 120V?
Yes.
Can you plug a 120v 20 amp wielder into a 240v 40 amp outlet?
No, it is not safe to plug a 120v 20 amp welder into a 240v 40 amp outlet. The voltage difference is too high and could damage the welder. It is important to match the voltage and amperage of the welder with the corresponding outlet.
How much voltage does a line with resistance of 10 ohms and a current of 20 amps?
V = i*r v = 2 * 60 v= 120v
120v to 16v 10w transformer how do you convert 16vDC to 2vDC to run an LED?
Divide the LEDs current into the voltage and derive a proper current limiting resistor value. 16/0.02=800 ohms. That is for a 20 ma LED.

What is the total current if a 60 ohm 40 ohm and 20 ohm resistors are all three connected in series across a 120 VAC source?
I = E ÷ R = 120V ÷ (60Ω + 40Ω + 20Ω) = you figure it out now
What size wire is required for 120v 5amp 250ft?
Use AWG #10 wire on a 20 amp breaker.
Can you plug a 120v 20 amp wielder into a 240v 40 amp outlet?

How many ohms is a 120 volts?
"Volts" is electrical pressure applied to a circuit; whereas, "ohms" is electrical resistance to that pressure. One cannot determine ohms from voltage without knowing either the current (in "amps") or power (in "watts"). A normal 120V household circuit can handle a maximum of 20 amps, so using ohm's law of resistance = voltage / current, the minimum resistance required in a 120V household circuit would be 6 ohms. Any less than 6 ohms will cause the circuit breaker to trip.
Why u shocked by alternating current and not by direct current?
alternating current is usually 120V or 240V direct is a car battery 12V 30 milliamps is fatal 20 milliamps is something you wont want to do often 10 milliamps you may feel easily if you are sweaty on a hot day and your bare belly is on a fender you may feel the 12V if your skin is dry on a cool dry day you may not feel 120V DC get you one muscular contraction you may be able to pull away using another limb AC contractions occur many times and you can break free with the affected muscles
Will be there any electrical connection to ultrasonic sensor of ultrasonic flowmeter and if it is present what type?
Any Sensor has to have an electrical connection to transmit signals from the sensor the the VDU. however it is a DC connection varying in Voltages between 24 and 120V, and current would be 4 to 20 mA
