Meter A:
Total resistance = 2 + 22 = 24 kΩ

Meter B:
Total resistance = 2 + 324 = 326 kΩ

Meter A is more sensitive

Which meter has a greater sensitivity meter A having a range of 0 - 15...
To determine which meter has a greater sensitivity, we need to compare the sensitivity of both meters. The sensitivity of a meter is determined by its full-scale deflection (FSD) and the resistance in series with it, which is called the multiplier resistance.

For meter A:
Range = 0 - 15 V
Multiplier resistance = 22 kΩ

To calculate the sensitivity, we can use the formula:

Sensitivity = Range / Multiplier resistance

Sensitivity of meter A = (15 V) / (22 kΩ) = 0.00068 V/Ω

Now, let's compare meter A's sensitivity to another meter, meter B, which we'll assume has a different range and multiplier resistance.

If the sensitivity of meter B is higher than 0.00068 V/Ω, then meter B is more sensitive.

If the sensitivity of meter B is lower than 0.00068 V/Ω, then meter A is more sensitive.

Without knowing the range and multiplier resistance of meter B, we cannot determine which meter has a greater sensitivity.
