Question

0.5A current flows though an electric heating device connected to230V supply Find the quantity of charge that flows through a circuit in 5 minutes

Answer 1

Answer:

150 C is answer

Explanation:

Firstly calculate the resistance using Ohm law R=(V/I) Then calculate the Total workdone i.e Heat produced in conductor E= (I*2 R T ) from joules law of heating .... And using E= V×Q and finally find the value of Q

Answer 2

Answer:

The quantity of charge that flows through a circuit is 150C.

Explanation:

The current is defined as the quantity of charge flowing through a device per unit of time. i.e.

$I=\frac{Q}{t}$            (1)

Where,

I=current through the device

Q=charge flowing through  the heating device

t=time during which the charge flows

From the question we have,

I=0.5A

V=230v

t=5min=5×60=300s

By putting the value of I and t in equation (1) we get;

$0.5=\frac{Q}{300}$

$Q=0.5\times 300=150C$

Hence, the quantity of charge that flows through a circuit is 150C.
