Is potential difference directly or inversely proportional to resistance?
Potential difference is directly proportional to resistance according to Ohm's Law. This means that as resistance increases, the potential difference across a component also increases, assuming the current remains constant.
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.
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.
The ratio of the potential difference across a metallic conductor to the current in the conductor is known as?
That is the resistance, measured in ohms.
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 happen is the potential difference across is double?
If the potential difference across a circuit is doubled, the current flowing through the circuit will also double, assuming the resistance remains constant. This is because Ohm's Law states that current is directly proportional to voltage when resistance is held constant.
A switch is connected in a series with a 75-W bulb to a source of 120V. what is the potential difference across the switch when it is closed?
If the switch, light bulb, and source are all connected in series and the switch is ideal (has no resistance), then the switch acts as a short. There is no potential difference across the short.
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.
What happens when unknown resistance is changed to other armin wheatstone bridge?
Changing the unknown resistance in a Wheatstone bridge will result in an imbalance in the circuit, causing a potential difference across the bridge. This potential difference can be used to determine the new value of the unknown resistance by adjusting other known resistances until the bridge is balanced again.
How does the potential difference across the bulb in a flashlight compare to the terminal voltage of the batteries used to power the flashlight?
The potential difference across the bulb in a flashlight should be slightly lower than the terminal voltage of the batteries used to power the flashlight. This is because there is a small internal resistance in the batteries which causes a voltage drop across it.
Why pottential difference across different ends of the conductor is different in the series connection?
In a series circuit, the total potential difference provided by the power source is divided among the resistors. Each component experiences a portion of the total voltage drop based on its own resistance, resulting in different potential differences across each component. This is why the potential difference across different ends of the conductor is different in a series connection.
