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
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.
What will be the potential difference across a 50Ω resistor if a current of 500mA is flowing through it?
Potential difference equals current multiplied by resistance or E = IR therefore the answer to your question is 25 volts
What kind of relationship can be concluded about the voltage difference across a resistor and the curent flowing through it?
Ohm's Law Voltage = Current x Resistance
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 .
How could you prevent too much current from flowing through a wire?
by resistor installation
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.
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
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.
