An inductor, battery, resistance, and ammeter and switch are connected in series. If the switch, initially open, is now closed,

Tanzania [10]

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

Answer: 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 $V=R.I$

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:

$I=\frac{V}{R}$

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

The Electric Field 9.0m from a +25μC charge is 

salantis [7]

The electric field intensity generated by a single point charge is given by

$E(r)=k\frac{q}{r^2}$

where

k is the Coulomb's constant

q is the charge

r is the distance from the charge

In this problem, the charge is $q=25 \mu C=25 \cdot 10^{-6} C$ and we are asked to calculate the field at distance $r=9.0 m$ , so the electric field is

$E(9.0 m)=(8.99 \cdot 10^9 Nm^2C^{-2})\frac{25 \cdot 10^{-6} C}{(9 m)^2}=2775 V/m$

A balanced 3-wire, 120/240V, single-phase circuit is connected so that the ungrounded conductors are from different transformer

sasho [114]

Answer:

$0\%$

Explanation:

A 3-wire, 120/ 240 V circuit from a three-phase delta transformer contains two ungrounded conductors and one grounded conductor. The grounded conductor carries the unbalanced current when the circuit is not balanced.

A neutral conductor has the same equal potential between it and all ungrounded conductors of a 3-wire system.

The current on the neutral conductor is $0\%$ percent of the ungrounded conductor current.
