You should draw a diagram of each for this question.
In a series circuit, the resistors experience the same current. In a parallel circuit, they have the same voltage drop. Therefore, the equivalent resistance is calculated differently for a series and parallel circuit.
Ohm's law: V=IR
Resistance keeps a circuit from shorting.
Answer and explanation:
The efficiency of the LED bulb is 20% while The efficiency of the Inc bulb is 1%.
The lightbulb efficiency can be defined as the quotient between the amount of usable light and the amount of electrical power output. For the efficiency of the CFL Bulb:
Therefore:
Answer:
<h3>The answer is 9 kg</h3>
Explanation:
To find the mass given the force and acceleration we use the formula
where
f is the force
a is the acceleration
We have
f = 18 N
a = 2 m/s²
We have
We have the final answer as
<h3>9 kg</h3>
Hope this helps you
Answer:
B Electrocoagulation.
It is a process that involves the use of high frequency current to cause coagulation usually of protiens in tissues and also the destruction of abnormal tissues making use of the heat generated by the electric current. This tissue could be a tumor or some other kind of lesion.
Explanation:
The passage of electric current through the electrode (second electrode that has been sterilized) in contact with the tissue causes the molecules within them to vibrate. This leads to a sharp increase in the temperature of the tissue due to the heat generated by the electric current. This is what causes the coagulation of the proteins within the tissue and also burns the tissue thereby effectively destroying it.
Electrocoagulation also called electrocautery, electrofulguration, and fulguration.
