Question

In the given circuit diagram find the value of
potential difference and current across the 10 12
resistor

(A) 30 V, 3A
(B) 30 V, 5A
(C) 15 V, 3 A
(D) 15 V, 2 A


And please tell me the chapter name from where this question is? Please chapter name ??

Answer 1

Answer:

chapter is current electricity .

Answer 2

(i) R=6+3=9Ω

V=4V

I=

R

V

=

9

4

=0.45A

(ii) 12 ohm and 3 ohm are in series

R=12+3=15Ω

I=

R

V

=

15

4

=0.27A

p.d across 12 ohms= IR=0.27×12=3.24V
