Oh, dude, it's like basic math here. So, you just divide the voltage by the resistance to get the current. In this case, 12 volts divided by 3 ohms equals 4 amps. So, the current in this circuit would be 4 amps. Easy peasy lemon squeezy!

What is the relationship between volts per amp in an electrical circuit?

The relationship between volts and amps in an electrical circuit is defined by Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R) in the circuit. In other words, volts per amp is a measure of resistance in the circuit.


How many volts equal amps?

What you are asking is kinda like asking how many oranges in an apple.Voltage is the measure of electrical potential.Amperage is the measure of electrical flow quantity.A good illustration is a water pipe: you can have high pressure (volts) but unless the water is allowed to flow the quantity of water is zero. (amps)


How much current in amps flows through a circuit with a 100 resistance?

You don't have enough information in your question, you need to include the voltage as well. One relevant equation is V = I * R where V: Voltage, I: Amps, and R: Resistance. When you have the voltage divide the Ohm resistance into that and you'll get your amps.


What happens to amps when you increase the resistance of a circuit?

When you increase the resistance in a circuit, the current (amps) in the circuit will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, so as resistance increases, current decreases.


According to Ohm's law what are the two variables that affect the amount of current in a circuit?

According to Ohm's Law, the two variables that affect the amount of current in a circuit are voltage (V) and resistance (R). The current (I) flowing through a circuit is directly proportional to the voltage applied across it and inversely proportional to the resistance in the circuit.

How to figure amps in an electrical circuit?

To figure out the amps in an electrical circuit, you can use Ohm's Law, which states that Amps Volts / Resistance. Measure the voltage across the circuit and the resistance of the components in the circuit, then divide the voltage by the resistance to calculate the amperage.


How do you measur ampere?

You use an "amp gauge" to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!


What is the resistance of the circuit if the voltage is 230 volts and the current flowing is 5 amps?

What is the resistance in a simple circuit if voltage is 12 volts and current is 3 amps?

Ohm's Law: Resistance = voltage / current, so 12 / 3 = 4 ohms.


How many amps does a circuit with 110 volts and a resistance of 7ohms have?

The amperage in the circuit can be calculated using Ohm's Law: Amperage = Voltage / Resistance. Plugging in the values, we get Amperage = 110V / 7ohms = 15.71A. Therefore, the circuit would have approximately 15.71 amps of current flowing through it.


How do you work out amps in an electrical circuit?

Current symbol I =voltage/resesistance I=V/R for direct current (dc) and for a resistive load in alternating current (ac)


Using ohm's law what is the formula to find the resistance in a circuit?

Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)


Do resistors lower volts or amps?

Current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.


How much resistance should be on a 5.0 kw heat strip?

Depends on the voltage. Wattage is Volts x Amps. Resistance (ohms) is Volts divided by Amps. So on a 120V circuit, it would draw 41.66 amps. To do that, it would need a resistance of 2.88 ohms. But on a 240V circuit, it would draw 20.83 amps. That would require a resistance of 11.52 ohms. Determine the circuit voltage, then use that to figure the amps, then use that result to calculate the resistance necessary.
