1 answer:

5 0

Answer: Protect people from severe and sometimes fatal electrocution by monitoring for electrical leakage to ground.

Explanation:

The main purpose of a Ground Fault Circuit Interrupter (GFCI) is to ensure that when a person gets electrocuted, the flow of electricity is cut off quickly so that no serious injuries or death occurs.

It works by monitoring the electrical leakage to the ground by checking to see if the current going to and coming from the equipment differ by a certain amount and if it does, the GFCI will interrupt the circuit.

tigry1 [53]

Answer:

Current yield=5.6%

The current yield is the proportion of the current price of a bond earned as annual interest payment.

Current yield = annual interest payment/bond price

Annual interest payment = coupon rate × face value

= 5.44% × $2000

= $108.8

Current yield

= annual interest payment/price

= $(108.8/1,930.36) × 100

= 5.6%

Typically explained, Economies of scale (EOS) are the advantages or benefits a firm achieves due to increase in production or operation which in turn leads to decrease in per unit costs.

Here in this question, it is evident that the only way economies of scale could be achieved is by increasing the large scale production techniques that leads to lower per-unit costs of production for the firms.

Hope this clear things up.

Thank you.

Answer:

Year 3 cashflow:

current system: 243,360

alternative system: 102,240

Present cost:

current system PV -$971,665.9146

alternative system PV -$1,075,964.17

Explanation:

Current Scenario:

42,000 inspection cost

Repairs:

1,520 identified x $75 = 114,000

Refunds:

480 units x $182 = 87,360

Total yearly cost: 243,360

PV of an annuity of $243,360 during 5 years:

Present Value of Annuity

$C \times \displaystyle \frac{1-(1+r)^{-time} }{rate} = PV\\$

C 243,360

time 5

rate 0.08

$243360 \times \displaystyle \frac{1-(1+0.08)^{-5} }{0.08} = PV\\$

PV $971,665.9146

New Scenario:

Inspection cost: $42,000 + $25,000 = $77,000

Repair cost: 350 units x $41 = $14,320

Refunds: 50 units x $182 x 120% = $10,920

Total yearly cost: $102,240

F0 cost:

470,000 workers trainings

210,000 purchase cost

Total F0 cost: 680,000

Present Value of Annuity

$C \times \displaystyle \frac{1-(1+r)^{-time} }{rate} = PV\\$

C 102,240

time 5

rate 0.08

$102240 \times \displaystyle \frac{1-(1+0.08)^{-5} }{0.08} = PV\\$

PV $408,214.6742

PV of residual value:

PRESENT VALUE OF LUMP SUM

$\frac{Maturity}{(1 + rate)^{time} } = PV$

Maturity 18,000.00

time 5.00

rate 0.08

$\frac{18000}{(1 + 0.08)^{5} } = PV$

PV 12,250.50

Net present value:

- 680,000 -408,214.67 + 12,250.50 = 1,075,964.17
