Three $2\ Ω$ resistors, $A$ , $B$ and $C$ , are connected as shown in figure. Each of them dissipates energy and can withstand a maximum power of $18\ W$ without melting. Find the maximum current that can flow through the three resistors?

Circuit diagram

The formula to calculate current from power formula is

$\begin{array}{l} I^{2} = \frac{i}{i} \\ = i \\ I = i A \end{array}$

The sum of the individual currents in each parallel branch in a parallel circuit the main current flowing into or out of the parallel branches. The potential difference across separate parallel branches are the .

The current flowing through

$B$ and

$C$ is given as

$\begin{array}{l} \frac{i}{i} \times Current flowing through i \\ = \frac{i}{i} \times i \\ = i A \end{array}$
