How is an ammeter connected to a circuit?
a. one end is connected to the positive end of the battery and the other end is connected to the negative end.
b. it is connected parallel to the circuit.
c. only one end is connected to the circuit.
d. it is in series with the circuit.
e. it is connected perpendicular to the circuit.

d. It is in series with the circuit.

Explanation:

As we know that ammeter is used to measure the electric current in a given branch of the circuit.

Here when some current flows through the ammeter then it will measure that current as its reading.

So here ammeter always measure the current that is passing through it and hence we connect the ammeter in series with the branch of circuit in which we wish to measure the current.

So here correct answer is

d. It is in series with the circuit.

ill do it for 100, also this isnt 80 its 40
