An inductor, battery, resistance, and ammeter and switch are connected in series. If the switch, initially open, is now closed, what is the current's final value

The question is incomplete. Here is the complete question.

An inductor, battery, resistance and ammeter and switch are connected in series. If the switch, initially open, is now closed, what is the current's final value?

a. zero

b. Battery voltage divided by inductance

c. battery voltage times inductance

d. battery voltage divided by resistance

d. battery voltage divided by resistance

Explanation: Resistance, voltage and current are related by Ohm's Law, which is explained as the current that passes through a conductor is directly proportional to the applied voltage. The constant of proportionality between them is Resistance.

Ohm's Law is represented by

Inductor is a component that stores magnetic energy when electricity is applied to it.

Ammeter is an object constructed to measure electric current of a circuit and it is always connected in serie.

So, in the circuit, when the switch is closed, the "only way" for current to pass through is because of Ohm's Law, which means its magnitude will be:

Then, the correct alternative is d. voltage divided by resistance.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
