Question

When starter motor of a car is switched on for 0.8 s, a charge 24 C passes through the coil of the motor. Calculate the current in the coil.​

Answer 1

Answer :-

• Current → 30A

Given :-

• Amount of charge → 24 C
• The Time taken → 0.8 Sec

Have to find :-

• Calculate the current in the coil.

Solution :

As we know the formula for calculating the current.

$\: \: \: \: \: \large{ \bf{ \boxed{ \bold{ I = \dfrac{Q}{t} }}}}$

Where,

" I " → Current flow

" Q " → Amount of charge

" T " → Time Taken

From given we know,

• Charge = 24 C
• Time = 0.8 Sec

Therefore, simply substituting the values in it, we get

➹ I = 24/0.8

Removing decimal.

$\\ { \bold{ I = \dfrac{Q}{t} }}$

$\\ { \bold{ I = \dfrac{240}{8} }}$

➹ I = 30 Amperes

Hence,

30 Amperes of current will flow.

Answer 2

Answer:

When considering a flow of electric charges, the quantity of charge which passes is given by:

Quantity of charge=Rate of flow of charge×time,i.e. Q=It

Hence, current is given as: I= Q/t=24/0.8

=30 A
