**(1)**

Applying Kirchoff's loop rule to the left loop:

ε - (30.0)i_{1} = 0

i_{1} = ε/30.0 = 8.00/30.0 = 0.267 A

The batteries shown in the circuit in (Figure 1) have negligibly small internal resistances. Assume that & 8.00 negligibly small internal resistances. Assume that-8.00 V and R = 21.9 Ω.
