Answer:
I = 0.2 A
Explanation:
The current flowing across each resistor in a series arrangement is the same throughout the circuit. So in order to calculate the current, we must first find the equivalent resistance of all three resistors. The equivalent resistance of the resistors connected in series is given as:
Now we use Ohm's law for the current:
<u>I = 0.2 A</u>
Answer:A generator is the appropriate device to be used.
Explanation:
A generator is a device which transforms mechanical energy to electrical energy.
The different parts of a generator includes:
- Engine, alternator, fuel system, voltage regulator, lubricating system, cooling and exhaust system, Battery charger and control panel.
The generator works on the principle of electromagnetic induction which states that
that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field. This movement creates a voltage difference between the two ends of the wire or electrical conductor, which in turn causes the electric charges to flow, thus generating electric current.
Therefore, the use of a generator is the best device for the campers to provide electrical power source for their heaters and light in the cabin.
The Answer is= 7.8 x 10^4
Answer: D
X and Y
Explanation:
X The least amount of magnesium Took in magnesium
Y Slightly less magnesium than the cell Took in magnesium
Because active transport occurs when ions or molecules move from less concentration region to high concentration region through semi membrane with the help of some energy.
