Can you frame your thinking in terms of potential difference across each lamp, and how this varies as the slider is moved from Y to X?GreenTea09 said:I chose option A as current prefers to flow through the path of least resistance.
A potential divider is a circuit that divides the input voltage into smaller voltages. It consists of two resistors connected in series, and the output voltage is taken from the connection between the resistors.
A potential divider works by using the principle of voltage division. The voltage across each resistor is directly proportional to its resistance, so the ratio of the resistances will determine the ratio of the output voltage to the input voltage.
The equation for calculating the output voltage in a potential divider is Vout = (R2 / (R1 + R2)) * Vin, where R1 and R2 are the resistances of the two resistors and Vin is the input voltage.
The output voltage in a potential divider is affected by the ratio of the two resistors, the input voltage, and the tolerance of the resistors. Any changes in these factors will result in a change in the output voltage.
Potential dividers are commonly used in electronic circuits to provide a specific voltage level for components such as sensors, LEDs, and transistors. They are also used in voltage regulators and power supplies to achieve a desired output voltage.
