How Does Resistance Affect Current
What happening is resistance is affecting the current.
How does resistance affect current. Resistance is an independent variable ohm s law. Resistance is the property of an object and resistivity is the property of the substance of which the object is made. Non linear resistance does not obey ohm s law but has a voltage drop across it that is proportional to some power of the current. Adding more resistance to a circuit will alter the circuit pathway s and that change will force a change in voltage current or both.
Beyond these core electrical concepts there is a practical distinction between the two varieties of current. Resistance increases voltage. When you are decreasing the resistance this current value is going up. Ohm s law gives current as a ratio of voltage to resistance.
Voltage equals current times resistance however reducing voltage and or current does reduce power which reduces temperature. V i x r. This is given from. Resistance is pure and is not affected by frequency with the ac impedance of a resistance being equal to its dc resistance and as a result can not be negative.
1 answer mark c. You can calculate the resistance of the filament by rearranging the equation. Resistance or impedance decreases electrical current per ohm s law. 1 volt flowing through 1 ohm of resistance produces 1 ampere of current.
So the resistance is 120 ohms. As per v ir usually v voltage value is constant when we are increasing the resistance the amount of current flowing in the circuit is going down. Adding resistance will affect. Some current is direct and some current is alternating and this is a very important distinction.
