Answer:
B=1.04*10^{-4}T
Explanation:
An infinite wire produces a magnetic field that can be computed with the formula:
where m0 is the magnetic permeability of vacuum (4pi*10^{-7}Tm/A), I is the current of the wire (2.50A) and r is the perpendicular distance to the wire in which B is calculated (3cm=3*10^{-2}m). By replacing we obtain:

Answer:
The reading on the ammeter A₁ , should be 2 Amp.
Explanation:
Given circuit shows all the bulbs are connected in parallel and ammeter A(T) at the source reads 6 Amp.
So, as the bulbs are in parallel connection, the current gets divided equal to each bulb.
so, the reading on the ammeter A₁ , should be 2 Amp.
But it will show 6 Amp, which is three times of the required value(2 amp).
This is because there was a mistake while making the circuit connections.
Instead of making connections as given circuit, the connections were made different as uploaded circuit.
Instead of connecting ammeter A₁ to only one bulb, it is connected to all the bulbs.
To correct this, remove the wire connecting ammeter and the second bulb.
And connect the second bulb directly to the switch.
