The reading of the ammeter in the circuit arrangement is zero (0 A).
How to calculate the reading of the ammeter?
The reading of the ammeter is the measure of the current flowing in the circuit.
In a series circuit, the total voltage is obtained by adding the voltage in the circuit. In this arrangement the positive terminal of one voltage source is connected to the negative terminal of the next voltage source.
However, in the given circuit arrangement, the positive terminal of one voltage source is connected to the positive terminal of the next voltage source.
The voltage across the entire voltage sources is calculated by finding the sum of the differences of the opposing voltage sources.
Vt = V₂ - V₁
Vt = 1.5 V - 1,5 V
Vt = 0 V
Since the resultant voltage in the circuit is zero, the reading of the ammeter will be zero.
