How can one determine the potential difference in a circuit?
To determine the potential difference in a circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). By measuring the current flowing through the circuit and knowing the resistance of the components, 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.
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.
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 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.

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 can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
How is electrical resistance calculated?
Resistance (Ohms) = Potential Difference (Voltage) / Current (Amps)
Current is proportional to the potential difference and inversely proportional to its?
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance

A steeper slope indicates a higher resistance, while a shallower slope indicates a lower resistance.
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.
Graph of resistance of filament lamp against potential difference?
As potential difference increases in a filament lamp, resistance also increases due to an increase in temperature. The relationship between resistance and potential difference in a filament lamp is non-linear due to the temperature-dependent nature of resistance in the filament material. At low voltages, the resistance is relatively low, but as the temperature of the filament increases with higher voltages, the resistance also increases.
