In the circuit shown in the following figure, the voltage across the R1 = 5.50 O

Question

In the circuit shown in the following figure, the voltage across the R1 = 5.50 Ohm resistor is 27.0 V. what are the emf of the battery and the current through the 6.00-Ohm resistor? (Let R2 = 1.00 Ohm) Epsilon = _____ V I = __________ A A capacitor is charged to a potential of 13.0 V and is connected to a voltmeter having an internal resistance of 3.45 Mohm. After a time of 3.50 s the voltmeter reads 3.0 V (a)What is the capacitance? ___________ F (b) What is the time constant of the circuit? _______ s

Explanation / Answer

E = 31.9Volts

I = 5.318A

C = 0.69 micro Farad

tau = 3.4 s
