Question

a charge of 100c flows through a bulb in 5 minutes How much current is flowing through the bulb​

Answer 1

Answer:

Q = 100 C

t = 5 min = 5 × 60s = 300s

∴ I = Q/t

I = 100/300

 =  1/3 A

 = 0.33 A

Answer 2

Given:

• Total charged flown = 100 Coulomb.
• Time taken = 5 minutes.

To find:

• Current in circuit ?

Calculation:

• Current is defined as the flow of charge through the cross section of a conductor in a definite time period.

• In other words, current can be calculated as the value of charge divided by the time taken.

$\therefore \: i = \dfrac{q}{t}$

• Putting value in SI UNITS:

$\implies i = \dfrac{100}{5 \times 60}$

$\implies i = \dfrac{100}{300}$

$\implies i = \dfrac{1}{3}$

$\implies i = 0.33 \: amperes$

So, current flowing through the circuit is 0.33 Ampere.
