Question

2. State whether the statement is true or false :

(i) Current through any resistance is inversely proportional to the potential difference across the resistance.

ii) pH increases with increase in acidic strength.​

Answer 1

Answer:

1) True

2) False: because pH goes on decreasing while increase in acidic strength

Answer 2

Answer:

(1) The given statement is False

(2). The given statement is False

Explanation:

(1). It is false because; acc to ohm's law , potential difference across the resistance is directly proportional to the current in the circuit. The proportionality sign is replace by the electric resistance and it increases with increases in temperature.

(2). it is false because; As the acidic strength increases; the pH value decrease. therefore it  is inversely proportional to the pH value. When the pH value increases the acidity decreases. the pH scale ranges from 0 to 14 with 7 as neutral; less than seven as acid and more than 7 is basic in nature. The lesser the value at the pH scale the more the acidic concentration.
