Complete Question:
What is the power in a circuit that has a current of 12 amps and a resistance of 100 ohms?
Answer:
D. 14,400 watts
Explanation:
The electrical power of an electric circuit can be defined as a measure of the rate at which energy is either produced or absorbed in the circuit.
Mathematically, electrical power is given by the formula;
This ultimately implies that, the quantity (current times voltage ) is electrical power and it is measured (S.I units) in Watt (W).
<u>Given the following data;</u>
- Current = 12 Amperes
- Resistance = 100 Ohms
To find the power in the circuit, we would use the following formula;
Power = I²R
Where;
- I is current measured in Amperes.
- R is resistance measured in Ohms.
Power = 12² * 100
Power = 144 * 100
<em>Power = 144,000 Watts</em>
Meter and second is the correct answer.
This is called average speed.Its really simple
Potential energy is the energy stored in matter because of
its position or because of the arrangement of parts.
Answer:
Semi conductors are part of the fourth group in periodic table.
Explanation:
Periodic table is the arrangement of chemical elements on the basis of their atomic number. So all the elements with respective valence electrons are placed in thir respective groups. . All the elements with valence electrons four are placed in the fourth group .Semi conductors is the common name given to the elements of 4th group. These elements dont have the tendency to either donate or accept.
The group 3 elements have three electrons in their valence shell and hence have a tendency to donate. Whereas the group 5 elements having five valence electrons accept to satisfy thir octet. The semi conductors exist between 3rd and 5th groups exhibiting different properties according to the temperatures and excitations provided.
