Question

(ANS. 47312)
6. A battery of 6 V is connected in series with
three resistors of 12 12,612 and 4Q as shown
in Fig. 4.59 is the current through each of the
resistors the same? Calculate the potential
difference across each resistor.
it is in series​

Answer 1

Answer:

For resistors in series,

R

eq

=R

=0.2+0.3+0.4+0.5+12

=13.4 Ω

By ohm's Law:

V=IR

eq

9=13.4I

I=0.67 A

When resistors are connected in series, current is same in all the resistors. Hence, current in 12 Ω resistor =0.67 A.
