Question

find the amount of current flowing through the circuit in 30 minutes and amount of charge containing in a circuit is 800 c​

Answer 1

Given:

• Time = t = 30 minutes
• Charge = Q = 800 C

To find:

• Current = I = ?

Formula used:

I = Q ÷ t

Solution:

Electric charge is defined as the excess or deficiency of Electrons.

First let us convert the time which is in minutes to seconds.

30 minutes

= 30 × 60 seconds

= 1800 seconds

Now, applying the given formula

I = Q ÷ t

⇒ I = 800 ÷ 30

⇒ I = 80 ÷ 3

⇒ I = 26.6 A

∴ The current flowing through the circuit = 26.6 Ampere

SOME MORE USEFUL FORMULA:

• Power = Voltage × Current
• Charge = Number of Electrons × Charge on 1 Electron
• Potential difference = Work done ÷ Charge
