What else can I help you with?
Does current flow through a resistor, or does it flow across a resistor?
Current flows through a resistor, not across it.
Does voltage flow across or through a resistor?
No. If a voltage is applied across a resistor, a current flows through it.
Is current is drop when it flowing through the resistor?
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
How does a resistor affect the flow of electricity in a circuit: does a resistor reduce voltage or current?
A resistor affects the flow of electricity in a circuit by reducing the current that flows through it. This reduction in current leads to a decrease in voltage across the resistor.
Does a resistor reduce current or voltage in an electrical circuit?
A resistor reduces the flow of current in an electrical circuit, which in turn affects the voltage across the resistor.
A 4000-Ω resistor is connected across 220 V what current will flow?
A 4000-Ω resistor is connected across 220 V will have a current flow of 0.055 A.Ohm's law: Voltage equals Current times Resistance
What is the current flow if you apply 12v across a 68 ohm resistor?
0.1764 amps
What does resistor perform?
A resistor's resistance is measured in ohms. The higher the resistance the less current will flow with a constant voltage applied across the resistor. In terms of Ohm's Law Voltage = Current x Resistance.
How do you install a resistor in an DC circuit?
It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load. To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow. To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.
If the potential difference across a resister decreases to zero the current does what?
If the potential difference across a resistor decreases to zero, the current flowing through the resistor also becomes zero. This is due to Ohm's Law, which states that current (I) is directly proportional to voltage (V) across the resistor (I = V/R). With no voltage to drive the flow of charge, the current halts.
How much current will flow through a 12 ohm resistor if 6 volts are applied across it?
Voltage / Resistance = Current, you do the math
Why is there no flow of electric current between 2 objects of equal resistance?
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
