Determine the following in the electric circuit given below.

As per the given question, the following can be determined:

Effective resistance of two 8 Ω resistors in combination 

⇒ R = \(\frac{R_1 R_2}{R_1 R_2} = \frac{8\ \times \ 8}{8\ + \ 8}\) = 4 Ω

Current that flows through 4Ω resistor

⇒ \(I = \frac{V}{R}= \frac{8}{4 + \frac{8 \times 8}{8+8}}\)

Potential difference across 4Ω resistance

⇒ V = IR = 1 × 4 = 4V

Disspated Power in 4 Ω resistor

⇒ P = I²R = 12 × 4 = 4W

Difference, if any, in ammeter readings

There is zero difference as because no current is seen to flow through the elements in a series circuit.
