What is the potential difference across a 1500 ohm resistor carrying a current of 0.075 A?
Potential Difference across a resistor is given by, Potential Difference = Resistance * Current = 1500 * 0.075 = 112.5 Volts
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.
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.
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.
What is the potential difference across a resistor that dissipates 24 W of power and has a current of 3 A?
Work it out yourself. PD=P/I, Where PD=Potential Difference, P=Power & I=Current
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 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
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
How much current is in a resistor of 1.8 k if the potential difference across the resistor is 4.0 X 10 V?
22ma. E=R/I
If there is a potential difference of 12 V across a resistor with 0.25 A current in it the resistance if the resistor is?
Resistance (Ohms) = Potential Difference (Volts) / Current (Amps) So, 12/0.25 = 48 Ohms.
What is possible unit for the product VI where V is the potential difference across a resistor and you is the current through the same resistor?
A possible/probable unit is Watts.
Does potential difference change with change in resistance?
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
