Question

plz answer it fast ​

Answer 1

The key is closed so this means that the circuit is complete.

Net resistance ,

Rs = R1 + R2 + R3

Rs = 5 + 8 + 12 = 25Ω

Current in resistor , V = IR

6 = I (25)

I = 6/25 = 0.24A

Reading of ammeter = 0.24A

Voltage,

V = IR, resistance = 12Ω

V = 6/25 x 12 = 72/25 = 2.88

Reading of voltmeter , 2.88v

Answer 2

reading of ammeter =current in the circuit
I =V/R
R= 5+8+12
=25ohm
V=6V
I =6/25
=0.24 A
so the reading of the ammeter is equal to 0.24A .

V=IR
=0.24×12
=2.88V
And the reading of the voltmeter is 2.88V .
