In the figure R1 = 123 ?, R2 = R3 = 58.8 ?, R4 = 67.0 ?, and the ideal battery has emf ? = 6.00 V. (a) What is the equivalent resistance? What is i (in A) in(b) resistance 1, (c) resistance 2, (d) resistance 3, and (e) resistance 4?

Explanation / Answer

a) 1/(1/58.8+1/58.8+1/67)+123

= 143.43 ohm

b) itotal = 6 V/143.43

= 0.042 A and IR1 or 0.042 A = IR1
