d) three ampere​

Answer 1

Answer:

Plz elaborate your question

Explanation:

29 ← what is this '29'

resistance of a heating coil is 300 and potential difference is 60V. current passing should be

fa ←{what is this} charge of one coulomb passing through a cross-sectional area in one second, current is

2 ←{what is this}

Answer 2

Answer:

Question 1 )

Resistance of the Heating Coil : 300 ohms

Potential Difference across the Resistor : 60 V

Current across the Resistor = ?

According to Ohm's Law,

⇒ V = IR

⇒ I = V / R

⇒ I = 60 / 300 = 1 / 5 = 0.2 A

Since the options have only 2 A, the question must have been Resistance equal to 30 ohms or Potential Difference equal to 600 V.

Question 2 )

Charge = 1 C

Time Taken for Crossing = 1 sec

Current = Charge crossing an Area per unit time.

⇒ I = Charge / Time

⇒ I = 1 C / 1 sec

⇒ I = 1 A

Therefore Option b) is the correct answer for Second Question.
