Question

a battery supply a charge of 50c through a circuit if the current drawn from the circuit is 750ma.find the time completely charged batterys

Answer 1

Given,
Q= 50c
I=750×10-3
so, I=Q/t. t=I/Q
750×10-3/50=15×10-3hr.

I hope it will help you

$\large\pink{\underline{\underline{\maltese{Given:-}\maltese}}}$

• Charge ; Q = 50 C
• Current ; I = 750 mA = 0.75 A

$\large\pink{\underline{\underline{\maltese{Find:-}\maltese}}}$

• find the time completely charged batterys.

$\large\pink{\underline{\underline{\maltese{Formula:-}\maltese}}}$

$\large\purple{\fbox{I = Q/t}}$

$\large\pink{\underline{\underline{\maltese{Solution:-}\maltese}}}$

$I = \frac{Q}{t}$

=> $t = \frac{Q}{I}$

=> $t = \frac{50}{0.75}$

=> $t = 66.67 sec$

=> $t = 67 sec$

=> $t = 1 min 7 sec$

$\\\bf\blue{Time\:taken\:to\: completely\: charge}$

$\bf\blue{the\: battery\:(t) =}\bf\purple{ 1 \:min \:7 \:sec }$
