Alicia, a physics student working on her lab assignment sets up the circuit shown in the figure. The reading of the voltmeter is 6.10 V and the reading of the ammeter is 2.80 mA. Assuming the voltmeter and ammeter are both ideal, calculate the following. R + 3.00 kQ i (a) the value of R (in k() KQ (b) the emf (in V) of the battery (c) the voltage (in V) across the 3.00 kQ resistor
