How would I find the Voltage across the open circuit

Engineering
1 answer:
Nimfa-mama [501]3 years ago
3 0

Answer:

  Vab = 80V

Explanation:

The only current flowing in the circuit is supplied by the 100 V source. Its only load is the 40+60 ohm series circuit attached, so the current in that loop is (100V)/(40+60Ω) = 1A. That means V1 = (1A)(60Ω) = 60V.

Vab will be the sum of voltages around the right-side "loop" between terminals 'a' and 'b'. It is (working clockwise from terminal 'b') ...

  Vab = -10V +60V +(0A×10Ω) +30V

  Vab = 80V

A ½-hp motor requires 120 volts. What amperage is required?
Zolol [24]

Answer:

  3.11 A

Explanation:

Use the given relations between power, horsepower, voltage, and current to find the current requirement for the motor.

  P = hp(745.7 W) = (1/2)(745.7 W) = 372.85 W

  I = P/V = (372.85 W)/(120 V) = 3.1071 A

The amperage required is about 3.11 A.

If p = .8 and n = 50, then we can conclude that the sampling distribution of pˆ p ^ is approximately a normal distribution.
defon

Answer:

It is true that the sampling distribution of the proportions is approximately a normal distribution.

Explanation:

Solution

Given that:

N = 50

P= 0.8

Thus

p ^ =√p(1-p)/n

p ^=√0.8 (1-0.8)/50

p ^= 0.0566

Therefore,we conclude that the sampling distribution of the proportions is approximately a normal distribution.

Why are today’s homes more likely to have dangerous levels of carbon monoxide than older homes?
Margarita [4]

Answer:

Carbon monoxide has no odor, color or taste,so  it cannot be detected by our senses. This means that dangerous concentrations of the gas can build up indoors and humans have no way to detect the problem until they become ill.
