Question

Find tge resultant resistance​

Answer 1

Answer:

hv dy gf fig dy CV hv ch Vvxxxxxxx

Answer 2

Answer:

in the above figure shows that

the voltage applied is 6volts

if the switch closes the resultant resistance is that the total resistance R=7+4x12/4+12=3

by ohms law I=V/R

i.e. v=6volts

R=3ohms

I=6/3=2Amps
