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.
Resistors A and B are connected in parallel If resistor B has twice the resistance of A what is the current taken by resistor B?
half of the current flowing thru resistor 1.... V=IR.
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.
The value of the resistor has 5 volts across it and has 20mA flowing through it?
The value of a resistor with 5 volts across it and 20 milliamperes of current flowing through it is 250 ohms. Ohm's Law: E = I R R = E/I
How are the plus and minus voltage signs determined for resistors?
Resistors have no polarity. The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).
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
Potential difference across resistor is doubled?
If the potential difference across a resistor is doubled, the current flowing through the resistor will also double, assuming its resistance remains constant. This relationship is described by Ohm's Law, where current is directly proportional to voltage when resistance is held constant.
How to find the potential difference across a resistor in an electric circuit?
To find the potential difference across a resistor in an electric circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). So, you can calculate the potential difference by multiplying the current flowing through the resistor by the resistance value of the resistor.
What is the relationship between the current flowing through a wire and the potential difference across it?
The relationship between the current flowing through a wire and the potential difference across it is described by Ohm's Law. Ohm's Law states that the current (I) flowing through a wire is directly proportional to the potential difference (V) across it, and inversely proportional to the resistance (R) of the wire. Mathematically, this relationship is represented as V I R.
A sentence for the word resistor?
the material we used is resistor because it did`t stop flowing.
Current times resistance equals what?
The voltage across a resistor multiplied by the current flowing through it equals the power dissipated by the resistor, according to Ohm's Law (P = V * I). So, the relationship between current and resistance is not directly related in that way.
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 is the voltage difference across a 30- resistor if a 0.5 amp current is flowing through it?
30 ohms x 0.5 amp, that is 15 v.
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.
What is a resistor What does it do in a circuit?
A resistor is a passive two-terminal electrical component that limits the current flowing in electrical or electronic circuits.
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.
Resistors A and B are connected in parallel If resistor B has twice the resistance of A what is the current taken by resistor B?
half of the current flowing thru resistor 1.... V=IR.
