Question

The current flowing through a lamp is 0 2
a. If the lamp switched on for one hour what is the total electric charge that passes through the lamp?
a.720 c
b.360 c
c.740 c
d.380 c

Answer 1

Answer:

Option (a) is correct.

Explanation:

Since we know that the current is the ratio of charge and time.

$i=\dfrac{q}{t}$.......................(1)

Where i=curent flow in the circuit,q=amount of charge flow in the circuit and t is the time taken by the charge to flow from one point to other.

We have given,

i =0.2 amp, t= 1 hour=3600 sec.

We need to find the total electric charge

Using equation (1) we get,

$0.2=\dfrac{q}{3600}$

After solving we get,

q =720 c.

So,option (a) is correct.

Answer 2

Answer:

It is given that an electric bulb draws a current of 0.2 ampere when the voltage is 220 volts. where, Q = Charge and t = time taken. Therefore, 720 C is the amount of electric charge flowing through it in one hour
