A.breakers
B.feeder cables
Cbonding equipment
D.grounded bus

Answers

Answer 1
B) feeder cables that is your answer
Answer 2

The correct option is d. Grounded bus.

The following information should be considered:

For the balanced loads, there should be the zero current.But for the unbalanced one there should be the current in the neutral wire. So connecting neutral to the ground in subpanel will permit the current and due to this there should be the risk of shocks. For preventing this, neutral bus should be completely isolated from the grounded bus.

Calculate the resistance of a circuit with 1.5 A and 120 V. Use the appropriate formula from the list of formulas on the
whiteboard
A 60 watts
60 ohms
C 80 ohms

Answers

Answer:

Option C (80 ohms) is the right answer.

Explanation:

The given values are:

Current,

I = 1.5 A

Voltage,

V = I20 V

As we know,

⇒  [tex]V=IR[/tex]

or,

The resistance will be:

⇒  [tex]R=\frac{V}{I}[/tex]

On substituting the values, we get

⇒      [tex]=\frac{120}{1.5}[/tex]

⇒      [tex]=80 \ ohms[/tex]
