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.
Answer:
Brachial vein.
Explanation:
Veins may be defined as the blood vessels that carries the blood towards the heart. The main function of the vein is to carry the deoxygenated blood into the heart.
Brachial vein is the deep veins that has the name as their arteries occupy. The brachial veins receive their blood from the palmar veins with the interosseous vein. The brachial veins include the ulnar vein, radial vein in upper limb and lower limb consists of popliteal veins.
Thus, the answer is brachial veins.
