To calculate the resistance, you can use Ohm's Law, which states that ( R = \frac{V}{I} ), where ( R ) is resistance, ( V ) is voltage, and ( I ) is current. Given a potential difference of 12 V and a current of 0.4 A, the resistance can be calculated as follows:
[ R = \frac{12 , \text{V}}{0.4 , \text{A}} = 30 , \Omega ]
Thus, the resistance is 30 ohms.

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.

How the declair one ohm resistance?
One ohm is the resistance through which a current of one ampere will induce an electrical potential difference of one volt. Ohm's Law: Resistance is Voltage divided by Current
How does current increase when potential difference increase?
Current increases with an increase in potential difference due to Ohm's Law, which states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R): (I = \frac{V}{R}). As the potential difference across a conductor rises, more voltage pushes charge carriers through the circuit, resulting in a higher current, assuming resistance remains constant. This relationship is fundamental in understanding how electrical circuits operate.

How can you calculate the potential difference between two points in a circuit?
To calculate the potential difference between two points in a circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). The formula is V I x R. By knowing the current flowing through the circuit and the resistance between the two points, you can calculate the potential difference.

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.

Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
How is electrical resistance calculated?
Resistance (Ohms) = Potential Difference (Voltage) / Current (Amps)
How does resistance after current?
Assuming you are asking "How does resistance altercurrent?", then the answer is that, for a given value of potential difference, the current is inversely-proportional to the resistance. E.g. doubling the resistance will reduce the current by half.
What does the slope of a graph potential difference vs current represent?
The slope of a graph of potential difference vs current represents the resistance of the component or circuit being analyzed. It is calculated using Ohm's Law: V = IR, where V is the potential difference, I is the current, and R is the resistance. A steeper slope indicates a higher resistance, while a shallower slope indicates a lower resistance.
What is the ratio of potential difference to the current of a circuit?
The ratio of potential difference to current in a circuit is known as resistance, measured in ohms (Ω). This relationship is described by Ohm's Law, which states that resistance equals voltage divided by current (R = V/I).
