Analyse the given electric circuit and answer the network: i) The equivalent resistance of the network T ii) The total electric current I in the circuit

The circuit shows two resistors, $R_1 = 60 \Omega$ and $R_2 = 30 \Omega$, connected in parallel.

The formula for two resistors in parallel is:

Comparing with the given options: A) $30 \Omega$, B) $60 \Omega$, C) $20 \Omega$, D) $90 \Omega$.
The correct option is $\boxed{\text{C) } 20 \Omega}$.

The dry cell provides a voltage $V = 3 \text{ V}$.
The equivalent resistance of the circuit is $R_{eq} = 20 \Omega$ (calculated in part i).

Ohm's Law states $I = \frac{V}{R_{eq}}$.

Comparing with the given options: A) $0.1 \text{ A}$, B) $0.05 \text{ A}$, C) $0.15 \text{ A}$, D) $0.00 \text{ A}$.
The correct option is $\boxed{\text{C) } 0.15 \text{ A}}$.
