We're going to use Kirchhoff's loop rule, which is:
We'll also use Ohm's law to help get the voltages.
From Ohm's law:
, where i is the current and R resistance.
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 circuit
a. 4 A
b. 2 A
c. - 2 A
d. - 1 A
