What 2 Factors Determine How Much Amperage Will Flow?
The two main factors that determine how much amperage will flow in a circuit are the voltage of the source supplying the electricity and the resistance in the circuit. According to Ohm's Law, the amperage (current) in a circuit is equal to the voltage divided by the resistance (I = V/R).
What tool can be used to test voltage resistance and amperage in a circuit?
A multimeter.
Doubling the resistance in a circuit will increase or decrease amperage?
If voltage remains constant and resistance is increased, the amperage will decrease per Ohm's Law.
What regulates the flow of electrons in an electrical circuit?
a. amperage and voltage b. the size and length of the wires c. voltage and resistance d. fuses and circuit breakers
How many amp is 21 volts?
To calculate the amperage, you need to know the resistance in the circuit. Amperage is calculated using Ohm's Law: Amperage (A) = Voltage (V) / Resistance (R). Without knowing the resistance, we cannot determine the amperage.
Does a voltage source have resistance?
Voltage source: is any source that voltage and amperage come from. Resistor: is any part of a circuit that consumes that energy!
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.
What does volts times amperage equal?
Voltage is equal to amperage time resistance. V=IR Therefore, I'd say voltage times amperage is equal to amperage squared times resistance. VI=IIR Really there's no point in multiplying the two. However, if you were to divide voltage by amperage, you would have the resistance of the circuit. V/I=R
How do you convert DC Voltage to DC Amperage?
You don't convert DC voltage to DC amperage. You get it automaticly when you have a resistance in your circuit. Scroll down to related links and look at "Ohm's law - Wikipedia".
What is the amperage in an electric circuit when the voltage 120 volts and the resistance is 40 ohms?
Ohm's Law states Voltage = Current x Resistance. You rewrite the equation as Current = Volts / Resistance to solve for current.
True or false if the voltage and resistance of a circuit stay constant the amperage can never change?
False. According to Ohm's Law, amperage (current) in a circuit is determined by the voltage and resistance. If either the voltage or resistance changes, the amperage will change accordingly to maintain a balance in the circuit.
How do you increase amperage without changing voltage or resistance?
You cannot increase amperage without changing voltage or resistance. Ohm's law states that voltage is current times resistance. You cannot change one alone. Not even changing frequency in a capacitive or inductive circuit will do this, because changing frequency represents a change in reactance, which is effectively a change in resistance.
