Find the reading In each ammeter and voltmeter. Explain briefly.
Question
1)In (Figure 1) , the total resistance is 12.0 kΩ , and the battery's emf is 35.0 V . The time constant is measured to be 16.0 μs
A)Calculate the total capacitance of the circuit.
B)Calculate the time it takes for the voltage across the resistor to reach 14.0 V after the switch is closed.
2)A power supply has a fixed output voltage of 12.0 V, but you need VT = 2.0 V for an experiment.
A) Using the voltage divider shown in the figure (Figure 1) , what should R2 be ifR1 is 10.0 Ω ?
B)What will the terminal voltage VT be if you connect a load to the 2.0 V terminal, assuming the load has a resistance of 6.0 Ω ?
