A circuit is constructed using two batteries and three resistors. R. What is the current /2 through resistor R2? Find an expression for /2 in terms of Va, Vb, R1, R2, and R3. Take the positive direction to be downward. R, Vb V 12 = -1.233 IncorrectFor the circuit shown in the gure. determine the magnitude 1' of the currents 12, I3 ., and I4 passing through batteries 2. 3. and 4, respectively. In each case. determine whether the battery is supplying power or being charged. The batteries and resistors in the circuit are assumed to be ideal and have the given properties. a. :33.0V s3 23.00V s3 =2].0V s4 = LSUV R. =1'mo R2 = 36.051 R3 = 23.051 Battery 2 is O supplying power. 0 being charged. Battery 3 is O supplying power. 0 being charged. Battery 4 is O supplying power. 0 being charged. A circuit consisting of three idea] batteries with voltages 3., 3'2, and $3, and three idea] resistors with resistances RI . R2, and R3. is shown in the gure. 3'1 2 28.0 V. 32 = 19.5 V, 3'3 2 34.5 V R1 = 4.90 k, R2 =14.0k. R3 2 3.00m Calculate the current Ip through point P. Let the sign of the current correspond to its direction. with "up\" being positive. OP W 31 3 You charge an initially uncharged 82.5 mF capacitor through a 22.1 2 resistor by means of a 9.00 V battery having negligible internal resistance. Find the time constant r of the circuit. T= S What is the charge Q on the capacitor 1.43 time constants after the circuit is closed? Q = C What is the charge Co after a long amount of time has passed? Q0 = C. A heart pacemaker res exactly 67 times a minute. Each time it res, a 29.0 HP eapaeiter is charged by a battery in series with a resistor to 0.532 of its full voltage. What is the value of the resistance R? Question Credit: OpenStax College Physics
