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.


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

The resistance of the circuit will be 46 ohms


What is the current in amps flowing through the circuit?

To determine the current in amps flowing through the circuit, you need to use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). The formula is I V / R. Measure the voltage across the circuit and the total resistance of the circuit, then plug the values into the formula to calculate the current in amps.


How do you work out the current in a circuit?

we can calculate the current in a commmon electrical circuit by this formulae i.e,I=V\R where i is the current flowing in the conductor, R is resistance , V is the voltage.. THE FORMULA IS CORRECT but the term conductor does not suffice an explanation since a conductor is low in resistance R= resistance not conduction.


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.


What factors determine the voltage induced in a wire?

V = I * R or I = ( V / R ) I = current (amps) V = Voltage R = Resistance The current in a circuit depends on the applied voltage and the resistance of the circuit.


How many amps will a 260 ohms resistor on a 120 volt circuit use?

Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260


How to calculate amps in a circuit?

To calculate amps in a circuit, use the formula: Amps Volts / Ohms. This formula helps determine the current flowing through a circuit based on the voltage and resistance present.


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.


What voltage is required to sustain a current of 0.50 through a light bulb resistance of 190?

The voltage of a circuit with a resistance of 250 ohms and a current of 0.95 amps is 237.5 volts. Ohms's law: Voltage = Current times Resistance


How do you calculate amps in an electrical circuit?

To calculate amps in an electrical circuit, you use Ohm's Law, which states that Amps (I) Volts (V) / Resistance (R). This formula helps you determine the current flowing through the circuit based on the voltage and resistance present.
