Question

Find out the reading of ammeter and voltmeter in the circuit given below 4 resistors of 2 ohm,3ohm,3ohm,4ohm. With ammeter in series and voltmeter parallel to 2ohm resistor.battery 6 volt

Answer 1

Explanation:

4 resistor in series

R s = 2+3+3+4 =12 ohm

R=V÷I

12=6/I

1. I=1/2=O.5 amp (current remain same in series)

4resistor in parallel not need to find out direct put

1. R=V/I
2. 2=6/I
3. I=3 ( current divide in parallel connection)

total R=12 by 2 ohm resistor in parallel 12/4 =3 ohm

hope it help mark as a brainlist

Answer 2

Answer:

total resistance

$r _{s} = r_{1} + r_{2} + r_{3} + r_{4}$

$r_{s} = 2 + 3 + 3 + 4$

$r_{s} = 12 \: ohm$

$v = i r$

$6 =12 \times i$

$i = 0.5 \: a$

Therefore

ammeter reading is 0.5 A

voltmeter reading is

voltmeter reading is V =IR

voltmeter reading is V =IR V = 12 v
