I think this is shown in the fine print on the second sheet . . .
The question starts out by saying that the scale uses two 3V cells in series .
That makes the total battery voltage 6 volts.
0.12 milliamperes = 0.00012 Amperes.
Resistance = (voltage) / (current in Amperes).
Resistance = 6 / 0.00012 = 50,000 Ω
To get 50,000 ohms of resistance, use Ohm's law (V = I * R) with a total voltage of 6V and a current of 0.12mA. Rearranging for R gives R = V/I, leading to the calculation of 50,000 ohms. Ensure you have the correct voltage and current values for accurate results.
