Resistance, or impedance, decreases electrical current per Ohm's law. Ohm's law gives current as a ratio of voltage to resistance: 1 volt flowing through 1 ohm of resistance produces 1 ampere of current. Resistance is the property of an object, and resistivity is the property of the substance of which the object is made.

How does resistance affect an electrical current? Ohm's law states that the current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance of a circuit.

I am going to investigate how the resistance of the wire affects a current flowing through a wire. I know that as resistance changes, current changes, as Ohm's law: I = V/R. If one part of an equation changes, the equal must be done to the opposite side. To detect how resistance affects current, I must first discover what factors affect resistance.

You are right that a low resistance in the voltmeter will not affect its measurement. The rule that a voltmeter resistance should be high compared with all resistors in the circuit is so that you can use the voltmeter in series resistance/impedance circuits without have to ask your question.

I'm in an elementary E&M physics class and thought I understood voltage and current pretty well until we got to resistance. I have a few questions concerning the effect of resistance on current that I hope somebody will be able to answer...I know I am missing something fundamental in my thought process.

1. Introduction The problem I am investigating is the effect of temperature on conductivity and resistance.Using a suitable conductor such as a copper wire, the following experiment will study whether the temperature of a wire will affect the flow of electrical current through a conductor.

For most circuits there is a voltage input so the input current is set by the effective resistance seen by the voltage input. With the effective resistance and voltage known, Ohm's law can find the input current (I). Water/electrical current: I = V/R; Higher resistance values (R) mean more energy is required to push a charge through the resistor.

So following the law a resistor must affect both voltage and current however the reality is that it only changes one size. To lower the voltage; To lower the current; This does not make much sense to me because in my understanding voltage and current must be lowered both but in the common LED resistor example it only affects one size:
