Question

answer for the following question please​

Answer 1

i havent touched physics in a long tym but is the answer 3V

Answer 2

Total resistance :

1/R= 1/10+(1/5+1/15)+1/60

= 1/10+1/20+1/60

= (6+3+1)/60

=10/60

=1/6

1/R=1/6

therefore total resistance = 6ohms

Now using ohm's laws ,

V=IR

V=1A×ohms

V=6 V

Net voltage across 20 ohm resistor = 6V

now 15 = 3/4*20 and 5=1/4*20

therefore 1/4 of 6 = 1.5 V

therefore voltmeter will show 1.5 V reading across 5 ohm reisitors
