Question

A current of 2A is drawn from a battery for 10s. i. How much charge is drawn in this time? ii. How much energy in joules is given to each coulomb of charge?

Answer 1

Answer:-

• Current=I=2A
• Time=t=10s
• Charge=Q=?

We know that

$\boxed{\sf I=\dfrac{Q}{t}}$

$\\ \sf\Rrightarrow Q=It$

$\\ \sf\Rrightarrow Q=2\times 10$

$\\ \sf\Rrightarrow Q=20C$
