What else can I help you with?
Is resistor measured in amps?
No, resistors are measured in ohms, not amps. Ohms represent the resistance offered by the resistor to the flow of current, whereas amps (amperes) represent the measure of current flowing through a circuit.
Why does a resistor heat up when an electric current flows through it?
Current moving through a resistor causes it to heat up because of the flowing electrons bumping into the atoms in the resistor.
Consider two identical resistors wired in series one behind the other If there is an electric current through the combination the current in the second resistor is?
Two resistors wired in series (no mater if they have the same resistor value or not) will always have the same amount of current flowing through them. Therefore, the current flowing through the second resistor will be equal to the current flowing through the first one. The current through every component in a series circuit is the same. The voltage across every component in a parallel circuit is the same.
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 resistor and its use and working?
resistor is a passive component which opposes the current flowing through a closed ckt. use in opposition of current in ckt .
Are resistor drops the voltage or current?
Resistors drop voltage by creating a voltage difference across themselves. This voltage drop is determined by the resistance value of the resistor and the current flowing through it, according to Ohm's Law (V=IR). The current passing through a resistor remains constant if the resistor is in series with other components in a circuit.
What is the purpose of the series resistor in a voltmeter?
The purpose of the series resistor in a voltmeter is to limit the current flowing through the voltmeter and protect it from damage due to excessive current.
What is true of a series circuit that has two resistors?
Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.
Why ohm-meter can't read the resistance value when current flowing through a resistor?
ohm meter puts current thru a resistor to measure voltage drop E / I = R if the circuit already has current flowing the numbers are meaningless
Can you provide some Ohm's Law practice questions for me to work on?
Here are some practice questions based on Ohm's Law: If a resistor has a resistance of 10 ohms and a current of 2 amperes flowing through it, what is the voltage across the resistor? A circuit has a voltage of 12 volts applied across a resistor with a resistance of 4 ohms. What is the current flowing through the resistor? If a circuit has a current of 0.5 amperes flowing through a resistor with a resistance of 8 ohms, what is the voltage across the resistor? These questions will help you practice applying Ohm's Law to calculate voltage, current, and resistance in electrical circuits.
Do you need to apply a load to see a voltage drop across a resistor?
You'll see a voltage drop across a resistor if current is flowing through it. It only has to be a part of a complete circuit, i.e. one in which current is flowing.
