Question 280: Current Electricity

Question

In the figure shown, what is the current
(in Ampere) drawn from the battery ? You are
given:
R1 = 15$$\Omega $$, R2 = 10 $$\Omega $$, R3 = 20 $$\Omega $$, R4 = 5$$\Omega $$,
R5 = 25$$\Omega $$, R6 = 30 $$\Omega $$, E = 15 V

Accepted Answer

Equivalent resistance of the given circuit
$${R_{eq}} = 45 + {{10 	imes 50} \over {10 + 50}} = \left( {45 + {{50} \over 6}} ight)\Omega $$
$$ \Rightarrow $$ $${{160} \over 3}\Omega $$
$$ 	herefore $$ $$I = {{15} \over {{{160} \over 3}}} = {9 \over {32}}A$$
