Question

calculate the resistance of R1 if V1 reads 3V

Answer 1

To calculate the resistance (R1) when the voltage (V1) reads 3V, we need additional information - specifically, the current (I) flowing through the resistor. Resistance is equal to voltage divided by current:

Resistance (R1) = Voltage (V1) / Current (I)

Without the current value, we cannot determine the resistance accurately.
