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).
