Answer 2

Total resistance in the circuit is 7.40 ohm, Current 0.81 A and Voltage 5.8 V

Explanation:

• Equivalent resistance = 1/8 + 1/12 = 20 / 96 = 0.20 ohm
• Total resistance = 0.20 + 7.2 = 7.40 ohm

Now current I = V / R

I = 6 / 7.4

I = 0.81 A

Total current in the circuit is I = 0.81 A

Now voltage V = I R

V = 0.81 x 7.4

V = 5.8 V

Thus total resistance in the circuit is 7.40 ohm, Current 0.81 A and Voltage 5.8 V
