Question

Q.33. On increasing the resistance in a
circuit, the current in it-
a) decreases
b) increases
c) remains unchanged
d) none of these​

Answer 1

Answer

• Option A (Decreases) is the answer

━━━━━━━━━━━━━━

• On increasing three resistance in a circuit the current in the circuit Decreases

• Here we concluded the Avatar on the basis of three Ohm's law

• Then ohm's law states that the potential Difference is equal to the product of this current and the resistance of a circuit

• That is, V = IR

• Which shows that V ∝ I and V ∝ R

• So as the current increase the resistance decrease and as the current decrease the resistance increase

• V ∝ 1/R

Answer 2

Answer:

✪ On increasing the resistance in a circuit, the current in it (a) decreases ☑ .

Explanation:

➢ 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 then the current will increase provide the resistance of the current does not change.

Relation between current, voltage and resistance :

‣ V = IR

⇒ I = $\dfrac{V}{R}$
