Explain How Resistance Affects Current In A Circuit

The circuit with the higher resistance will allow less charge to flow meaning the circuit with higher resistance has less current flowing through it.

Explain how resistance affects current in a circuit. Simple circuit showing voltage and resistance. This opposition to motion is more properly called resistance. The longer the circuit and the friction involved causes less current to get through it. For a given voltage how does increasing resistance affect the current in the circuit.

Now substitute amperage as the water and the diameter of the pipe as resisitance. 1 volt flowing through 1 ohm of resistance produces 1 ampere of current. Based on your answers to questions 1 and 2 write a simple equation to sum up the relationships among current voltage and resistance. And current that alternates back and forth through the circuit is known as alternating current or a c.

This would be analogous to increasing the resistance in in an electrical circuit and this would reduce the current flow. Aim of the experiment. This brings us back to georg ohm. To investigate how changing the length of the wire affects its.

Current tends to move through the conductors with some degree of friction or opposition to motion. Think of water moving through a pipe a smaller pipe will not allow as much water to pass in the same amount of time as a larger pipe. The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the circuit to oppose current flow. It is connected in series.

For a given level of resistance how does increasing the voltage affect the current in the circuit. Use appropriate apparatus and methods to measure current and potential difference to work out the resistance. Current that flows in a single direction is called direct current or d c. Resistance or impedance decreases electrical current per ohm s law.

The ammeter does affect the flow of current in a circuit however the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. Ohm defines the unit of resistance of 1 ohm as the resistance between two points in a conductor where the application of 1 volt will push 1 ampere or 6 241 10 18 electrons. Resistance is the property of an object and resistivity is the property of the substance of which the object is made. Think of resistance as friction.

In electronics and electromagnetism the electrical resistance of an object is a measure of its opposition to the flow of electric current the reciprocal quantity is electrical conductance and is the ease with which an electric current passes electrical resistance shares some conceptual parallels with the notion of mechanical friction the si unit of electrical resistance is the ohm ω.
