The diagram below shows a circuit containing two lamps. what will ammeter 4 read?

In the given circuit, with lamps connected in parallel and a common circuit current of 2A, each lamp will have a current of 1A. Ammeter 4 (I4), connected in series with one of the lamps, will also read 1A. Given: I₁ = 2A (current in the common circuit) Vcell = 1.5V (voltage of each cell) Since the lamps are connected in parallel, they have the same voltage across them. Voltage across each lamp = Vcell = 1.5V Now, let's calculate the current passing through each lamp: I1 = I2 = I₁/2 = 2A/2 = 1A Since ammeter 4 (I4) is connected in series with one of the lamps, it will measure the same current as that passing through the lamp. Therefore, ammeter 4 (I4) will read 1A. You can learn more about electrical circuits at brainly.com/question/27084657 #SPJ1
