Question

72J of work os done by a battery to cause the flow of 5.4×10^18 electrons through a conductor for 3 minutes . find the p.d. of the battery

Answer 1

Potential difference= work/charge

work=72joule ,. charge= no.of electron×electronic charge , charge = 5.4×10^18×1.6×10^-19 , charge = 8.64×10^-1. , potential difference= 72/8.64×0.1 after solving it p.d. is 83.34 volt

Answer 2

$\huge\frak\red{AnSwer}$

$potemtial \: difference \: = \\ \frac{work}{cgarge}$

work =72 joule

charge = number of electrons × electronic charge

$charge \: = 5.4 \times {10}^{2} \times 18 \ \\ \times 1.6 \times {10}^{2} - 19$

$charge \: = \: 8.64 \times {10}^{2} - 1$

potential difference = 7218.64 × 0.1

$after \: solving \: it \: ...$

potential difference if the Battery is 83.34 volt .

$hope \: its \: helpful \: for \: uh \:$
