Answer 1

$\large\bold{\underline{\underline{Question:-}}}$

Compute the no. Of electrons passing per min. Through an electric bulb of 60w 220v.

$\large\bold{\underline{\underline{Answer:-}}}$

Power (P) = 60 W

Voltage (V) = 220 V

$\boxed{ \rm{Current(I) = \frac{Power(P)}{ Voltage(V)}}}$

$\rm I = \dfrac{60}{220}$

$\rm I = 0.27 \: A$

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　

Time (t) = 1 minute = 60 s

$\boxed {\rm{Charge (Q) = Current(I) \times Time(t) }}$

$\rm Q=0.27 \times 60$

$\rm Q=16.2 \: C$

　　　　　　　　　　　　　　　　

$\sf Electrons \: in \: 1C \: charge = 6.25 × 10</p><p>$

$\sf 1C \:of~ charge = 6.25 × {10}^{18}~electrons$

　　　　　　　　　　　　　　　　

$\sf 16.2C \: Charge =16.2 \times 6.25 × {10}^{18} electrons$

$\sf {\underline{\underline{16.2C \: Charge = \red{101.25 × {10}^{18}}~electrons.}}}$
