Question

An electric iron draws 0.6amper when voltage is 100volts. Calculate amount of electric charge flowing through it in 1 hour.​

Answer 1

electric charge is 2160 C

Answer 2

ANSWER

Given,

Current = 0.6 A

Potential difference or Voltage = 100v

Time= 1 hour.

Now, we know that

Q = it

where,

Q = electric charge

i= Current flowing through the conductor.

t = time.

But first we will convert the time in seconds.

Hence, we know that

1 minute = 60 seconds

So, 60 minutes(1 hour)= 60×60 = 3600s.

Now, we get =>

Q = (0.6)A × 3600s

=>Q = 2160 Coulombs.

Remember some formulas =>>>

1) Q = It

2)V = IR (Ohm's law)

3)P= VI and P = V^2/R

4)H = I^2Rt (Joules Law of heating)

5)P= work done/time = W/t
