Question

session, maste CH21 HW Problem 21.40 Find the curent that flows through the battery Express your answer using two significant figures Acruit onsists of a 120-V battery connected to three resist n (44.20 and 140 )insenes. AE Submit PartB Find the ponerdal difference across the 44 resistor Express your answer using two significant figures. Submit Request Answer Part C Find the potenaal diference across the 20 resis oc Express your answer using two significant figures. Submit Request Anewer Part D Find the pooraal dfronce across the 140 resistor Express your answer using two significant figures. MacBook A

Explanation / Answer

A) TOTAL Resistance = 44+20+140 = 204ohms
Current = V/R = 12 / 204 = 0.0588 A = 58.8 mA

B) V = I*R = .0588 * 44 = 2.5872 V

C) V = I*R = .0588 * 20 = 1.176 V

D) V = I*R = .0588 * 140 = 8.232 V
