Answer:
it is a very good question...
Explanation:
the equation linking voltage current and resistance is v = i multiplied by r.
to cabinet the voltage you can use the formula v = IR and put the values of i and r.
the rest of the questions can also be done by the same way.
for calculating the energy e way would multiply voltage with current including time.
hope it helps.
pls mark me as the brainliest...

Answer:
(i) v= Ir
Explanation:
since v is directly proportional to I and r is constant
