Entirely answer some or all of them in place of questions in

Entirely, answer some (or all) of them in place of questions in the main the exam, or answer all of them in addition to all questions in the main the exam. It is possible to earn 115% on this test. The circuit below contains two real batteries, each having significant interna resis Battery #1 has an EMF of 6.00 V and an internal resistance of 1.00 ohms. Battery #2 has an EMF of 3.00 V and an internal resistance of 2.00 ohm. These two batteries are connected in series with two resistors R\\ - 2 00 ohms an The current in the 6.00 Volt battery is equal to a. 1.00 A. b. 1.50 A. c. 0.500 A. d. 2.00 A. e. 0 A. The potential difference across the terminals of battery #1 from point 3 to point b is equal to a. 6.00 V. b. 5.50 V. c. 6.50 V. d. 5.00 V. e. 7.00 V. The potential difference across the terminals of battery #2 from point C to point d is equal to a. 5.00 V. b. 3.00 V. c. 1.00 V. d. 4.00 V. e. 2.00 V

Solution

Let the current be ! anti clockwise

applying kirchoff\'s law

6+I*2-3+2*I+1*I+I*1 =0

so I=.5 A

21) c is answer

22)6-.5*1 = 5.5 V so b is answer

23) 3+.5*2 = 4 V
