Answer 1

Answer:

12.It should be washed off, or at least brushed off, immediately after contact. The dust is a severe respiratory irritant and in dusty areas, respiratory protection should be worn.

13.a)Ohm's Law: Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

Answer 2

Answer:

Explanation:

Ohm's Law states that the potential difference between two points is directly ... This means electric current will decrease with increase in resistance and vice versa. The graph of V (potential difference) versus I (electric current) is always a straight line. potential .... NCERT Exercise Solution · NCERT Exercise Solution-2 · Quiz ...
