Question

return of 1, 2, 3 ohm are connected in the form of a triangle if a 1.5 volt cell of negligible internal resistance is connected across 3 ohm resistor the current flowing through this resistance will be​

Answer 1

Explanation:

Fig1

1ohm and 2ohm resistors are connected

in series. Therefore effective resistance

= sum= 3ohm

Now the two 3ohm resistors are connected in parallel(fig.2), so

1/R=1/3+1/3=2/3

R=3/2ohm

we know current I=V/R

=1.5×2/3

=1A

Hope it helps
