Question 354: Current Electricity

Question

In the figure shown, what is the current
(in Ampere) drawn from the battery ?
You are
given:
R
1
= 15$$\Omega $$, R
2
= 10 $$\Omega $$, R
3
= 20 $$\Omega $$, R
4
= 5$$\Omega $$,
R
5
= 25$$\Omega $$, R
6
= 30 $$\Omega $$, E = 15 V

Accepted Answer

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