Expert Solution
Concept
According to Ohm's law
V = IR
Where V = Voltage, I = Current, R = Resistance
Answer
Battery voltage Vo = 10 V
R = 5 Ω
Two R resistors are in parallel. Thus equivalent resistance of two R resistors is
Now R and R1 are in series so equivalent resistance of the circuit is
Req = R + R1
Req = 5 + 2.5
Req = 7.5 Ω
Now using Ohm's law
The current through the battery is given by
