The primary coil of a transformer has N1 = 275 turns, and its secondary coil has N2 = 2,200 turns. If the input voltage across t

he primary coil is Δv = (160 V)sin ωt, what rms voltage is developed across the secondary coil?

Answer:

Secondary voltage of transformer is 905.23 volt  

Explanation:

It is given number of turns in primary of transformer N_1=275

Number of turns in secondary N_2=2200

Input voltage equation of the transformer

\Delta v=160sin\omega t

Here v_{max}=160volt

v_{rms}=\frac{160}{\sqrt{2}}=113.15volt

For transformer we know that

\frac{V_1}{V_2}=\frac{N_1}{N_2}

\frac{113.15}{V_2}=\frac{275}{2200}

V_2=905.23Volt

Therefore secondary voltage of transformer is 905.23 volt

WHY does an acceleration cause velocity to increase
harkovskaia [24]

Answer:

When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. ... Acceleration occurs anytime an object's speed increases or decreases, or it changes direction.

Describe the difference between the currents that exist in the wires leading to a capacitor when these wires are connected to (a
krek1111 [17]

Answer:

Explanation: In DC circuit, the current will flow for a short time, which is required to charge the capacitor. Once you switch it on, it spikes and the gradually decreases to almost zero (0) as the capacitor becomes fully charged.

In an AC circuit, the circuit acts as if the current is flowing throw the plates whereas is not actually flowing. The circuit acts like the AC is flowing through the capacitor.

Lukalu is rappelling off a cliff. The parametric equations that describe her horizontal and vertical position as a function of t
andre [41]

Answer:

2.5 s, 5 m

Explanation:

The equations for the horizontal and vertical position of Lukalu are:

x(t) = 8t\\y(t) = -16t^2 + 100

we can find the time it takes her to reach the ground by requiring that the vertical position becomes zero:

y(t) = 0

So we find:

0=-16t^2 +100\\16t^2 = 100\\t=\sqrt{\frac{100}{16}}=2.5 s

The horizontal distance of Lukalu instead will be given by the equation for the horizontal position, substituting t = 2.5 s:

x=8t = 8 \cdot 2.5 s =5 m
