Question

If W is the work done in moving a charge $Q$ from a point $A$ to another point $B$. The potential difference $V_B-V_A$
is given by, $V_B-V_A=\frac{W}{Q}$
Also, if a charge $Q$ flows through a conductor, an electric current is said to exist in the conductor and its magnitude
is given by,$I=\frac{Q}{t}$
; where $\text{'}t\text{'}$ is the time for which charge $Q$ flows through the conductor.
An electric bulb draws a current of $0.2\mathrm{A}$ when the voltage is $220\mathrm{V}$. Calculate the amount of electric charge flowing through it in one hour.

Answer 1

If W is the work done in moving a charge $Q$ from a point $A$ to another point $B$. The potential difference $V_B-V_A$

is given by, $V_B-V_A=\frac{W}{Q}$

Also, if a charge $Q$ flows through a conductor, an electric current is said to exist in the conductor and its magnitude

is given by,$I=\frac{Q}{t}$

; where $\text{'}t\text{'}$ is the time for which charge $Q$ flows through the conductor.

An electric bulb draws a current of $0.2\mathrm{A}$ when the voltage is $220\mathrm{V}$. Calculate the amount of electric charge flowing through it in one hour.
