Answer:
Option D, both A and B
Explanation:
The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.
Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.
Hence, both potential difference and voltage drop occurs across the circuit,
Option D is correct.
Is this a question? True or false?
Answer:
If amoeba specie placed in the sea water, it will die because sea water contains excess of salts which adversely affect the growth of amoeba.
Explanation:
Amoeba is unicellular organisms i. e. made of a single cell. They are eukaryotic organisms i. e. having true nucleus. Amoeba is found in fresh water lakes and hot spring. Amoeba is not able to live in sea water because sea water contains salt which are not good for amoeba.
