What does a resistor do in an electric circuit?
Limits current flow and drops voltage.
How much current will flow through a 2.4 kilohm resistor when 7.2 kilovolts is applied?
Divide the voltage by the resistance in order to obtain your answer.
What do Electrons do not easily flow through?
A Resistor
What does the variable resistor do in a circuit?
It is used to vary the voltage/current flow in a circuit.
How does a transistor function as an amplifier?
A: The small base current will control the collector current flow by adding a resistor this changes of current flow will be evident as a voltage amplifier.
Does voltage flow across or through a resistor?
No. If a voltage is applied across a resistor, a current flows through it.
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 current flow through a resistor or across a resistor?
Normally through the resistor's internal construction. It flows through any part of the resistor that has low resistance- be it anywere. And then there's this. It might be that one should consider that current flows through a resistor and voltage is dropped across a resistor. Perhaps this is where the question began. The former is fairly straight forward. The latter can be vexing. Voltage is said to be dropped across a resistor when current is flowing through it. The voltage drop may be also considered as the voltage measureable across that resistor or the voltage "felt" by that resistor. It's as if that resistor was in a circuit by itself and hooked up to a battery of that equivalent voltage.
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 much voltage is required to cause 8mill of current to flow through a 10kilo resistor?
V = IR = 8x10-3 (8 mA) * 10x103 (10k) = 80v
Does a resister use current?
It may be better to say that a resistor allows current flow through itself rather than to say that a resistor is a device that will "use" current. It does "resist" current flow, and thus limits it to some degree depending on its resistance. (More resistance means more limiting of current flow.) The resistor "drops voltage" as well limits current. A resistor "feels voltage" from some source, and the voltage it "feels" is said to be the "voltage drop" of the resistor. The voltage drop is the voltage that could be measured across that resistor with a meter.
How does a resistor limit current or voltage in an electrical circuit?
A resistor limits current in an electrical circuit by impeding the flow of electrons, which reduces the amount of current passing through it. This, in turn, helps regulate the voltage in the circuit by creating a drop in voltage across the resistor.
Does current flow through a resistor, or does it flow across a resistor?
Current flows through a resistor, not across it.
How does an ammeter work?
An ammeter is a low voltage voltmeter in parallel with a small resistance resistor. Current flow through the resistor creates a voltage drop across it which is then measured by the voltmeter.
How did the current before the resistor compare with the current after?
Current flow would be the same through the resistor, since it's in series, but the voltage would be slightly reduced based on the resistance. If you have 2 resistors in parallel, the current will divide through each resistor, and the voltage stays the same. PLL Ohm's law and water flow - PLL
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.
How may type of resistors in diode?
None. A diode does not have a resistor in it. Diodes and resistors are different devices used for different purposes. For example, increasing current flow through a resistor increases the voltage drop across the resistor. Increasing current flow through a diode (within the diode's capabilities, just the same as a resistor) will actually decrease the voltage drop across the diode (once the diode "turns on" this voltage variance will be fairly small, though).
