Question

1. An electrical bulb drws a current of 1.25 A for 10 mins. Calculate the amount of electric charge that flows through the circuit?
Explain in detail​

Answer 1

Answer :

›»› The amount of electric charge that flows through the circuit is 750 Coulombs (C).

Explanation :

Given :

• Electric current = 1.25 A.
• Time = 10 mins.

To Find :

• Electric charge that flows through current = ?

Formula required :

Formula to calculate the amount of electric charge that flows through current is given by,

→ I = Q/t.

Here,

• I is the Electric current.
• Q is the Electric charge.
• t is the Time.

Units,

• The unit of Electric current is Ampere (A).
• The unit of Electric charge is Coulomb (C).
• The unit of Time is second.

Solution :

Firstly we will convert the unit of time from minutes to seconds.

→ Time = 10 mins

→ 1 mins = 60 secs

→ Time = 10 × 60

→ Time = 600.

We know that, if we are given with the electric charge and time then we have the required formula, that is,

→ I = Q/t.

By using the formula to calculate the amount of electric charge that flows through current and substituting all the given values in the formula, we get :

→ 1.25 = Q/600

→ Q = 1.25 × 600

→ Q = 125/100 × 600

→ Q = 125 × 6

→ Q = 750.

Hence, the amount of electric charge that flows through the circuit is 750 Coulombs (C).

Answer 2

Answer:

✪ Given :-

• An electrical bulb a current of 1.25 A for 10 mins .

✪ To Find :-

• Calculate the amount of electric charge that flows through the circuit.

✪ Solution :-

We know that ,

✰ Q = I × t ✰

Given in the question,

⋆ Electric current = 1.25 A

⋆ Time = 10 mins = 60 × 10 = 600 second

ATQ :-

⇔ Q = 1.25 × 600

➽ Q = 750 Coloumb

Therefore, the amount of electric charge that flows through the circuit is 750 Coloumb.
