What is the voltage drop across a resistor of 300 kilo ohm?
What is the amount of current flowing through the resistor? Voltage drop is dependent on the current. Ohm x Amps = Voltage drop
When the current traveling through a resistor is increased what happens to the voltage that travels through the same resistor?
Your question reveals fundamental misunderstandings about the nature of electricity.'Voltage' is simply another word for 'potential difference', and a potential difference appears across opposite ends of the resistor; it doesn't 'travel through' that resistor! Current, on the other hand, DOES 'travel through' the resistor and is caused by the potential difference across the resistor.Resistance is the ratio of potential difference to current. So if the resistance remians unchanged when the current through it doubles, then it has happened because the potential difference has doubled.
What is the voltage drop of a 1k ohm resistor?
It depends on the current going through it. Ohm's law: Voltage equals current times resistance.
How do you find the voltage drop over a resistor?
To find the voltage drop over a resistor, you measure it with a voltmeter connected across the resistor. You also need to make sure the impedance of the voltmeter is high enough to not shift the effective resistance more than the required accuracy of the measurement.
What are the losses in resistors?
The power lost in a resistor is(the current through the resistor) times (the resistance) watts. That's the same thing as(the voltage across the resistor)/(the resistance)watts.
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.
What is the current drop across the resistor?
The correct question is what is the voltage drop across a resistor or the current flowing through the resistor using Ohm's Law where Voltage = Current x Resistance
What is the use of resistor in the circuit?
A resistor develops a voltage differential when current is passed through it. Ohm's law: Voltage is current times resistance.
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.
What is the voltage drop across a resistor of 300 kilo ohm?
What is the amount of current flowing through the resistor? Voltage drop is dependent on the current. Ohm x Amps = Voltage drop
What is the rule for voltage across each resistor?
Volt across a resistor = resistance x current through the resistor.
What is the current through the 150 ohm resistor?
It depends on the voltage applied across it. But the maximum current is limited by the power-rating of the resistor (power divided by the square of the voltage).
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.

What kind of relationship can be concluded about the voltage difference across a resistor and the current flowing through it?
POWER=VI. V=voltage I= current
A current of 2.0 A flows through a 20 Ω resistor What is the voltage?
