Five identical resistor each of resistance `R = 1500 Omega` are connected to a 300 V battery as shown in the circuit. The reading of the ideal ammeter A is

Options

A. `1/5A`
B. `3/5A`
C. `2/5A`
D. `4/5A`

Answer

B

Explanation

In the given circuit , all the five resistors are connected in parallel to 300 V battery.
Therefore , the potential difference across each resistor is
V = 300 V
and by Ohm's law current through each resistor is
`I=V/R=(300 V)/(1500 Omega)=1/5A`
Since the three resistance are connected to the right of ammeter, hence the reading of the ideal ammeter A
`=3I=3(1/5A)=3/5A`
