If a toy car with a resistance of 2 ohms is connected to a 3v battery how much current flows through the car?
Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).
How micro ohm meter work in detail?
A current is passed through a resistor and the voltage drop is measured on the other side. It follows Ohm's law by a given current and voltage you can measure the resistance of a resistor by V=IR.
Using Ohm's law what is the formula to find amperage in a circuit?
Take your circuit voltage and the power of the appliances and divide.E is voltage I is amperage and P is power or wattage. P=ExI Example. 3500 watt heater draws ? Amps on 220Volts I=P/E I= 3500w/220v I= 15.9Amps
How much current flows through a resistance of 300 ohms if the power source is 15 volts?
Ohm's Law Voltage = Current x Resistance Answer is 15/300
What does I stand for in the Ohm's Law formula?
I is the current ( Amps) in the Ohm`s Law formula; V= I*R

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
What is the current of a 25 ohm heater operating at 240 V?
12 amps
What is the current through the 150 ohm resistor?
It depends on the voltage applied across it. But the maximum current is limited by the power-rating of the resistor (power divided by the square of the voltage).
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
What is a unit used to measure resistance?
The " Ohm " is. 1 ohm is the resistance across which 1 volt of EMF appears when the current through it is 1 Ampere.
What is the voltage drop of a 1k ohm resistor?
It depends on the current going through it. Ohm's law: Voltage equals current times resistance.
How the declair one ohm resistance?
One ohm is the resistance through which a current of one ampere will induce an electrical potential difference of one volt. Ohm's Law: Resistance is Voltage divided by Current
When a 10 ohm resistor is connected in parallel to a 15 ohm resistor what percentage of the total current will flow through the 10 ohm resistor?
There will be 20 amps flowing through the 5 ohm resistor. We could do some math and all to figure voltage drops and some other things, but let's cut to the chase and see what's happening. Based on what we know about series circuits and about parallel circuits, we can shred this in nothing flat. So let's. First, we're told 30 amps flows in the circuit. That's the total current, and it will be the current through the first 10 ohm resistor. It has to be. The the 30 amps "splits" to flow through the parallel network of the 10 ohm and 5 ohm resistors. That's 30 amps that has to "split" and some will go through the 10 ohm resistor and some will go through the 5 ohm resistor. With me? Sure. Now for the "trick" here. Since the 5 ohm resistor has only half the resistance of the 10 ohm resistor, twice as much current will flow through it as the 10 ohm resistor. Make sense? Yup. Let's finish this. Since there is twice as much current flowing in the 5 ohm resistor 'cause it's got half the resistance of the 10 ohm resistor, if we have "x" amount of current flowing in the 10 ohm resistor, then we'll have "2x" amps of current flowing in the 5 ohm resistor. That's "3x" amps total, and the "3x" amps equals 30 amps. See through it now? There will be 10 amps flowing through the 10 ohm resistor, and 20 amps flowing through the 5 ohm resistor. Piece of cake.
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source. What is the current running through the 120 ohm resistor?
1amp
