Problem: For the circuit shown in Fig. let R1 = 5 Ω, R2 = 15 Ω, R3 = 10 Ω, ε1  = 60 V, ε2 = 80 V, ε3 = 10 V and I1 = 2A. Find the value of the current I2 in the circuita. 4 Ab. 2 Ac. - 2 Ad. - 1 A

FREE Expert Solution

We're going to use Kirchhoff's loop rule, which is:

ΣV=0

We'll also use Ohm's law to help get the voltages.

From Ohm's law:

V=iR, where i is the current and R resistance.
