Question

(a ) Draw the circuit consisting of a battery of five $2 V$ cells, $5 o h m$ resistor, $10 o h m$ resistor, $15 o h m$ resistor and a plug key. All connected in series
(b) Calculate the current passing through the above circuit when key is closed.

Open in App

Solution

Current $I$ through the circuit is

$I = \frac{V}{R_{1} + R_{2} + R_{3}}$

$= \frac{10}{30} A$

$= 0.33 A$
