Problem: Consider the circuit shown below. Suppose four resistors in this circuit have the values of R1 = 13 Ω, R2 = 7.5 Ω, R3 = 7.7 Ω and R4 = 10 Ω, and that the emf of the battery is 18 V.Find the current through each resistor using the rules for series and parallel resistors

FREE Expert Solution

Equivalent resistance for resistors in parallel for 2 resistors:

Req=R1R2R1+R2

Equivalent resistance for resistors in series:

Req=R1+R2+...+Rn

Current:

i=VR

R2 and R4 are in series.

R24 = 7.5 + 10 = 17.5 Ω
