Question

Find the equivalent resistance between points A and B. If the resistors of 3ohm and 4 ohm is connected in series and 10 ohm, 5ohm and 3ohm is connected in parallel and a battery of 12v is connected.​

Answer 1

Since Resitor of 3ohm and 4ohm are connected in Series.

=>equivalent Resistance=3ohm+4ohm

=>equivalent Resistance=7ohm.

Since Resistor of 10ohm,5ohm and 3ohm are connected in parallel.

=>1/equivalent Resistance=1/10 + 1/5 + 1/3

= 3+6+10/30

=19/30

=>Equivalent Resistance=30/19
