<span>The voltage drives the necessary force for an electromagnet to work. The strength of an electromagnet depends on the electric current which flows through its wires, but not on what drives the current. </span>

An LC circuit consists of a 3.400 capacitor and a coil with self-inductance 0.080 H and no appreciable resistance. At t = 0 the
Gnoma [55]

Answer:

Explanation:

charge on the capacitor = capacitance x potential

= 1.588 x 3.4

= 5.4 C  

Energy of capacitor  = 1 / 2 C V ² , C is capacitance , V is potential

=  .5 x 3.4 x 1.588²

= 4.29  J

If I be maximum current

energy of inductor = 1/2 L I² , L is inductance of inductor .

energy of inductance = Energy of capacitor

1/2 L I² = 4.29

I² = 107.25

I = 10.35 A

Time period of oscillation

T = 2π √ LC

=2π √ .08 X 3.4

= 3.275 s

current in the inductor will be maximum in T / 4 time

= 3.275 / 4

= .819 s.

Total energy of the system

= initial energy of the capacitor

=  4.29  J

hram777 [196]
One possible unit is liter, which is a basic unit in metric system. 1 liter=10 cm^3, or 0.001 m^3, so we also know that other possible units include cubic centimeters or cubic meters, which are derived units, since they are derived from basic unit, meter, representing the length, breadth, and height of the cuboid.

valentinak56 [21]

Answer: Pairs of conductors carrying current into or out of the power-supply components of electronic equipment are sometimes twisted together to reduce magnetic-field effects. This is for reducing the area of the loop and hence reducing the inductance and suffer less interference or improving electromagnetic compatibility.

Explanation:  To find the answer, we need to know more about Twisted pairs.

<h3>What is twisted pairs?</h3>
  • Twisted pairs are simply conductors carrying current into and out of the power supply components of the electronic equipment, which are sometimes twisted together to reduce magnetic field effects.
  • It can be able to minimize the area of the loop around the circuit. thus, the magnetic field from each wire will cancels each other.
  • This will reduce the inductance as well as interference caused by the nearest fields.
  • Twisting them will defines a transmission line impedance.

Thus, we can conclude that, the twisted pairs are used for reducing the area of the loop and hence reducing the inductance and suffer less interference or improving electromagnetic compatibility.
